Java Plum - Syzygium cumini

  The Java Plum -  Syzygium cumini, Is a fast growing evergreen tree that reaches heights of 30-80 feet tall depending on the location/conditions planted.  It is considered a tropical tree and is a member of the flowering plant family Myrtaceae.  It grows in an erect single trunk they could be straight or crooked in form with a rounded crown.  The tree was introduced to Florida in 1911 by the USDA, it originated from Asia, specifically India and Burma.  It has become established in Maritime hammocks, lake margins, flatwoods and rocklands throughout Central and Southern Florida.  It is similar to the Malabar Plum Syzygium jambos but can be distinguished by the different sized leaves and fruit.  It is treated by the state of Florida as an invasive species. It can be found growing from Sea Level to 6000 feet above in the tropics. It grows best in areas with very high rain or humidity levels.

The leaves of the Java Plum are opposite, simple, thick, leathery, elliptic or oblong in shape with a rounded base and tip.  The upper surface of the leaves are lustrous and dark green in color with visible yellow lateral veins, the lower surface is a yellow-green in color and duller in sheen. Leaf blades are 7-18 cm long and 3-10 cm broad with a light yellow petiole of 5-25 mm long.  The leaves are said to smell similar to turpentine when crushed. The flowers are individually small in size only reaching 7 mm long, with 4 petals, fused in a rounded cap that opens and exposes a mass of white or pink threadlike stamens.  The flowers are produced in clusters 5-6cm long on the wood of the previous year.  Flowers on the Java Plum occur year round.  The fruit is fleshy with a single seed, it occurs as a oblong or ellipsoid berry that is 1-2.5 cm long and 2 cm in diameter.  When young the fruit is green becoming pink, red and then a purple-black.  The fruit matures year round the same as the flowers.  The pulp ranges from purple to white and is very juicy, with a sweet flavor in high quality varieties to astringent flavor in poorer varieties.

The products of the Java Plum are used for various purposes.  The fruit is used to make wine and vinegar, they are also a high source of Vitamin A and Vitamin C.  The fruit seeds are used in alternate healing processes, Unani and Chinese Medicine (digestive ailments) and Ayurveda (diabetes control).

"Dragon's Claw" or "Corkscrew" Willow - Salix matsudana

  The "Dragon's Claw" or "Corkscrew" Willow - Salix matsudana - is a cultivar of the Chinese (Babylon) Willow.  This cultivar grows very fast from cuttings made from the youngest (and often most curly) shoots.  It is considered medium to large in size and is a deciduous tree that grows in a primarily upright fashion. Chinese Willow's have a relatively short lifespan, estimated between 40-75 years in the wild. The Chinese Willow is a Native of Northeastern China. It has been planted heavily as an ornamental in the United States, Europe and Australia, so is seen often outisde of it's native area.

The leaves of this variety come out early in the Spring and often hold on well into December.  Even in Winter when the tree is bare the interest of the curls and curves in the branches remain, making it a beautiful year round addition to any landscape.  The leaves are green in color and when flattened look similar to the more common types of Willow (Weeping, Babylon and Coastal).  The female and male flowers appear as Catkins and are always on different trees. The branches are often used in floral arrangements or even as bonsai because of their unique curling habits.

The Corkscrew Willow is available at most major nursery's and makes a lovely addition to any landscape.  It may also be sold as a Dragon's Claw Willow or Curly Willow.

Sour Orange - Citrus x aurantium

   The Sour Orange - Citrus x aurantium is a small evergreen shrub or small tree that reaches heights of only 10-30 feet tall. The Sour Orange has been naturalized in Florida, Georgia and Texas, but originated in southeastern Asia and South Sea Islands (Fiji, Samoa, and Guam). Sour Orange is grown in orchards settings only in the Orient/various other parts of the world where its special products are of commercial importance, including southern Europe and some offshore islands of North Africa, the Middle East, Madras, India, West Tropical Africa, Haiti, the Dominican Republic, Brazil and Paraguay.

Image Citation:  NCSC Herbarium, Citrus ID, USDA APHIS ITP, Bugwood.org

The leaves of the Sour Orange are simply shaped ovate or elliptic, lustrous and deep green in color. The flowers are small, white in color and usually have 4 or 5 petals. The fruit is orange in color, round in shape with a thick almost leathery rind. Inside of the fruit is several separate sections or cells, each having at least a single seed. The fruit is fragrant, however it is generally too sour to be eaten on it's own. The primary use of Sour Orange is for the production of marmalade. The fruits are largely exported to England and Scotland for making marmalade.

Sawtooth Oak - Quercus acutissima

   The Sawtooth Oak - Quercus acutissima is most easily recognized by it's fringed acorn cup and narrow leave with bristle tipped teeth, resembling the teeth of a saw. It is a fast growing, deciduous shade tree that can reach heights of 30- 70 feet tall. Sawtooth Oak grows in an erect fashion with a single trunk and dense rounded crown. Originally introduced from Asia, generally found in planned landscapes and is reported to be naturalized in scattered areas from Pennsylvania South to North Carolina and Georgia, South to Louisiana. Sawtooth Oak is primarily planted for wildlife cover and food due to it's abundant fruit and fast growth habit. This species is sometimes used for urban and highway beautification as it is tolerant of soil compaction, air pollution, and drought.

Image Citations (Photos 1 & 2): Richard Gardner, UMES, Bugwood.org

Named for it's unique leaf edges, the Sawtooth Oak is a beautiful tree. The green leaves are alternate, simple, oblong or obvate, 12-16 pairs of sharp bristle tipped teeth, parallel veins and a lustrous upper surface and dull pale underside. The leaves add to the visual interest by beginning a brilliant yellow to golden yellow color in the Spring, turning dark lustrous green in summer and yellow to golden brown in the fall. The bark is dark gray in color with light gray scales that become deeply furrowed with age. The fruit is in the form of an acorn, the cup encloses 1/3 - 2/3 of the 1-2.5 cm nut. The acorn rim is adorned with long spreading hairlike scales that form a distinctive fringe.

Recommended for hardiness zones 5-9, the Sawtooth Oak can be found at most larger nurseries within those zones. Sawtooth Oak is also considered to be easily transplanted and hardy making it a wise choice for any landscape with room for a large spreading shade tree. It is similar to the Chinquapin Oak Castanea pumila in appearance, distinguished primarily by the difference in fruit.

Glossy Buckthorn - Frangula alnus

  The Glossy Buckthorn - Frangula alnus is a deciduous small tree or shrub that reaches heights of 20-25 feet.  Generally growing with multiple erect trunks in a shrubby form, with a stout crown.  Originally introduced from Europe about 200 years ago, Glossy Buckthorn has become established in weedy bogs, and other wetland areas.  Found as far North as Saskatchewan and Quebec South to West Virginia and Tennessee and West to Idaho and Colorado.  The Glossy Buckthorn is considered to be invasive in many areas and is treated as an invasive species in most Mid-Western wetland areas. 

Image Citation: Leslie J. Mehrhoff, University of Connecticut, Bugwood.org

Named for it's lustrous or glossy upper leaf surfaces, the Glossy Buckthorn is also easily identified by it's shrubby habit and clusters of red, purple or black drupes.  The bark of the Glossy Buckthorn is smooth and gray-brown in color with visible horizontal lenticels.  Young twigs are void of thorns and slender in form.  The leaves are alternate, oblong or oval in shape, with a rounded base and sharply pointed tip, sometimes having a wavy overall appearance.  The upper leaf surface is a dark lustrous or glossy green, while the undersides are a dull paler green.  Each leaf surface contains 5-9 pairs of obvious parallel lateral veins that curve to follow the margins.  The fall foliage turns a bright yellow and tends to remain on the tree/shrub long after others have lost their leaves. The flowers are bisexual, small in size and a creamy green or yellow-green in color, occurring in clusters at leaf axils each Spring.  The fruit is a rounded drupe, usually containing 2 seeds, 5-10 mm in diameter.  The fruit is red when young becoming a purple-black with maturity in the late Summer season.  

Image Citation: Leslie J. Mehrhoff, University of Connecticut, Bugwood.org

The Glossy Buckthorn is suited for hardiness zones 3-7 however it is not a recommended planting as it can overtake native species easily.  It's seeds are spread by various types of wildlife including birds and small mammals.  It easily adapts to not ideal growing conditions such as full sun, little sun and even high soil pH levels.

Cryptomeria - Cryptomeria japonica

     The Cryptomeria - Cryptomeria japonica is a monoecious ornamental evergreen tree that can reach heights upwards of 65-70 feet.  Growing in a slender, upright pyramidal fashion, it has unique short, sharp in-curved needles that are unique to this species and only the rare Taiwania (a similar species).  The needle-like leaves are 3-12 mm long and  spirally arranged. The bark is reddish brown to dark gray, fibrous and often peels off in strips. The cones are brown, slightly rounded with an apical point and are borne at the tips of the twigs in groups of 1-6.  The branching habit of this species is considered to be irregular and does not occur in a uniform fashion.

Image Citation (Mature Cryptomeria): Richard Webb, Bugwood.org

The Cryptomeria is native to only China and Japan, but has been successfully grown as an ornamental in the United States. In it's native range specimens are known to live more than 1700 years and reach diameters of almost 10 feet.  It is the national tree of Japan where it is often planted at temples and shrines.  In the US, the best specimens are found in regions with warm and moist summers.  The Cryptomeria is sometimes also called Sugi or Japanese Cedar.  This species prefers moist, rich, fertile, acidic, but well-drained soils in full sun and can only tolerate some light shade.  This tree is recommended for US hardiness zones 5-9 and is considered to be a low maintenance large specimen or screen tree.

Sassafras - Sassafras albidum

   The Sassafras - Sassafras albidum is a member of the Laurel family. Having only three varieties, two of which are native to China and Taiwan, and the other is native to the Eastern portion of the United States. Spreading by suckers growing from the roots, in it's natural habitat it is commonly found growing along the woods edge and fields or as the under story of a forest.

The fruit from the Sassafras is blue in color when mature starting at clear and red when young. Growing from red stems the fruit grow in an almost ornamental pattern. The fruit/berries are a favorite of small birds such as Finches in the Spring and Summer. Like the American Holly, the Sassafras is dioecious, meaning the pistallate and staminate flowers mostly grow on different trees.

Image Citation: Pennsylvania Department of Conservation and Natural Resources - Forestry Archive, Bugwood.org

The Sassafras tree has a unique scent that is recognizable even before the tree is in view, the oil that produces the scent is in the roots, the leaves and even the bark of the tree. Teas can be made by steeping the roots of the tree-Native American are recorded to have used this tea to treat many ailments. The oil was also used as the flavoring for traditional Root Beer prior to it's use being banned by the FDA in 1960 because of the Safrole found in the oil was thought to be a possible carcinogen. This banned was reversed partially in 1994 but new restrictions were put into place to be sure that the Safrole was removed prior to human consumption . File Powder, is a spicy herb made from dried and ground leaves. It was traditionally used by Native Americans in the South, and was adopted into Creole cuisine in Louisiana as a very commonly used ingredient.

Image Citations: Chris Evans, Illinois Wildlife Action Plan, Bugwood.org

The foliage of the Sassafras is very unique having as many as three varying type of leaves. The leaves can vary from single lobes, double lobed or mitten shaped to triple lobed. They are green in color during the growing season and in the fall put on a very beautiful show. The leaves will vary in color in the fall from Yellow, Orange, Scarlet and Crimson.

Ohio Buckeye- Aesculus glabra

   The Ohio Buckeye- Aesculus glabra - is a medium sized rounded crown Deciduous tree. Growing to only 20-40 feet tall at maturity, it has a moderate growth rate.  It is the most widespread of all of the Buckeyes in North America. Its range is on mostly mesophotic sites through Western Pennsylvania, Ohio, Southern Michigan on West to Illinois and Central Iowa, extending South to Kansas, Oklahoma, and Central Texas, East into portions of Arkansas, Tennessee, and Alabama. This tree thrives best in moist locations and is most frequently found along river bottoms and in streambank soils.  It has been planted frequently outside of its native range in Europe and the Eastern United States.  Different from the other Buckeyes because of two main features, first the leaflets have barely any visible stalk and second the husk of the fruit has short spines.  The Ohio Buckeye is sometimes referred to as the American Buckeye, Fetid buckeye, and Stinking Buckeye, the last because of the foul odor emitted when the leaves are crushed.

Image Citations (Photos 1, 2, & 3): T. Davis Sydnor, The Ohio State University, Bugwood.org 

Ohio Buckeye is polygama-monoecious, meaning it bears both bisexual and male flowers. The leaves are made up of unevenly toothed leaflets that all grow from the same point on the stem, they are green during the growing season and turn an almost grey when shifting finally to yellow in the Fall.  The flowers are a yellow green with prominent stamens growing as upright spikes. The bark is dark grey with shallow but coarse fissures leading into square scaly plates. It flowers in the Spring and fruits from summer to fall.  This tree also produces small, shiny, dark brown nuts with a lighter tan patch

"Buckeyes" has been the official Ohio State nickname since 1950, but it had been in common use for many years before.  According to folklore, the Buckeye resembles the eye of a deer and carrying one brings good luck.

Recommended for Hardiness Zones 3-7, Buckeyes are found in larger nurseries within their growth range.

Seven Sisters Oak - Mandeville, Louisiana

   At somewhere around 1500 years old, The Seven Sisters Oak is not only a Louisiana state champion but a National Champion Live Oak as well.  This tree is the largest Live Oak in the Country, with a circumference of 467 inches, a height of 68 feet and a very large crown spread spanning over 139 feet.  This tree is the only recorded champion with a crown spread that is nearly double the height of the tree itself.  It has held the title of National Live Oak Champion for over 30 years.

Image Citation: Chuck Cook, NOLA.com | The Times-Picayune archive

Contrary to many beliefs the tree was not named for the Seven main trunk sections of the trees but by a former owner, who was one of Seven Sisters.  This tree is registered with The Live Oak Society, who's members are only Live Oak Trees.  Since 1968, The Historic Seven Sisters Oak has remained the President of this unique society, becoming president when the Society's first President The Locke Breaux Live Oak died.

Image Citation: www.AmericanForests.org

Located in Mandeville, Louisiana, the tree resides in the front yard of a private residence, but still draws many visitors.  It is located in the quiet historic neighborhood of Lewisburg, just North of Lake Pontchartrain.  Because of it's sheer size it is said to be not well represented in photographs as the sheer size is hard to judge from one single angle.  This one surely calls for an in person visit next time you are in Louisiana!

Araucaria (Monkey Puzzle, Cook Pine, Norfolk Island Pine and Bunya Pine)

 The Araucaria (Araucarias) is a genus of trees mostly native to the Southern Hemisphere and including only 19 species. Four of these species have become popular ornamental plantings here in the United States (mostly in warm Southern portions of the Eastern Seaboard, and along the Atlantic and Gulf coastal plains). The four species that are found here in the US are Monkey Puzzle - Araucaria araucana (Molina), Cook Pine - Araucaria columnaris, Norfolk Island Pine - Araucaria heterophylla and Bunya Pine - Araucaria bidwillii. The Araucaria is one of three genera that make up the larger Araucariaceae family.

Bunya Pine  -  Image Citation: Dennis Haugen, Bugwood.org

Norfolk Island Pine - Thomas Smiley, Bartlett Tree Experts, Bugwood.org

All of the trees making up the Araucaria genus are tall evergreens with single straight trunks covered in rough dark gray-brown bark that is horizontally ridged. The trunks are generally covered in uniform whorls of branches that emerge at almost perfect right angles. The branches are covered in very dense or tight triangular or needle shaped evergreen leaves. The evergreen leaves are multi-veined and arranged spirally on each twig, branch and sometimes even on the trunk itself. Pollen Cones are large, one of the largest of any conifer. Seed Cones are dense and heavy, quickly disintegrating before or soon after falling. The inner seeds from the seed cone are considered a tasty treat to many varieties of native wildlife.

Black Oak - Quercus velutina

   The Black Oak - Quercus velutina - is also known as the Eastern Black Oak. It was sometime/ formerly called the Yellow Oak, because of the yellow pigment in it's inner bark. It is native to the Eastern and Central United States and is found in every East Coast state from Southern Maine to the Northern panhandle of Florida. It is found as far inland as Ontario, Minnesota, Nebraska, Oklahoma and even Eastern Texas. It is similar in appearance and often confused with the Northern Red Oak, Scarlet Oak and Southern Red Oak. Black Oak is known to hybridize with other members of the Red Oak group, and is a known parent in at least a dozen different named hybrids found today.

The leaves are simple, alternate, ovate and 4-10 inches long with 5-7 bristle tipped lobes on each one. They are a shiny green in color on the top during the growing season which shifts to a Yellow-Copper color in the Fall.

The Black Oak is monecious, the male flowers are borne on slender yellow to green catkins, while the females are reddish green and borne on short spikes in leaf axils that appear in spring with the leaves.

Image Citation: Rob Routledge, Sault College, Bugwood.org

The fruit, in the form of acorns that are 1/2 to 3/4 inch long, 1/3 to 1/2 of the Acorn is enclosed in a bowl-shaped cap. The cap scales on each Acorn are light brown and fuzzy. The Acorns mature every two years and appear in late summer into early fall. These Acorns are eaten by Wild Turkey, Whitetail Deer, Grouse and other small woodland mammals.

The bark is gray and smooth when young, becoming thick, very rough, almost black in sections and deeply furrowed. The inner bark is yellow-orange and very bitter tasting.

The Black Oak is not very common in the nursery trade because it can be difficult to transplant. When full grown the Black Oak can reach heights of 135 feet in ideal locations, however the average height is only 60-80 feet tall in most areas. The current Co-National Champion trees are found in Michigan (131 feet) and Connecticut (84 feet). Black Oaks have very prominent tap roots that ensures this species' survival under even poor growth conditions. It is recommended for hardiness zones 6-9. The Black Oak can be harmed by quite a few outside agents including Gypsy Moths, Oak Leaf Caterpillar, Oak Wilt, and Shoestring Root Rot to name a few.

China Fir - Cunninghamia lanceolata

   China Fir - Cunninghamia lanceolata, is most easily identified by the long, stiff, sharply pointed leaves and oval cones of leather like sharply pointed bracts near twig tips.  The China Fir was introduced to the United States and is considered a distinct ornamental.  Native to Southeast Asia.  In China the China Fir is considered to be an important timber tree and is referred to as the China Fir, even though it is a member of the cypress family.  It is fast growing and highly resistant to pests and diseases. It is widely used for landscaping and has medicinal uses.

The China Fir is a Monoecious evergreen tree that can reach heights of 90 ft tall with and irregular cylindrical crown. The leaves are needle like deep green, stiff, straight or slightly curved 3-6 cm and spirally inserted on each twig.  It is in leaf all year, in flower from January to May, and the seeds ripen from August to September annually.  The twigs are covered by dead leaves behind 2 or 3 years of living leaf growth. The cones are ovoid, reddish brown at maturity, 1 1/2 - 4 1/2 cm and made up of glossy, leathery, sharply pointed bracts, occurring at twig tips in groups of 1-4.  The bark is dark gray to reddish brown in color and fissured to expose the aromatic inner bark.  Plant has spines or sharp edges; use extreme caution when handling.

 

Image Citations (Photos 1, 2, & 3) : John Ruter, University of Georgia, Bugwood.org

China Fir has many uses outside of just being planted as an ornamental specimen.  The bark is a source of tannins and the branches produce an essential oil that is used in the perfume industry. The creamy yellow to white, fragrant wood is uniform in textured, straight-grained, lightweight and durable, though it will rot if it is continually wet. It is easily worked, sometimes turned and resistant to insect and termite damage. It is also used in construction such as ship building (mainly throughout Asia where it is harvested for lumber) where great strength is required. A good quality fuel and a charcoal can also be made from the wood.

White Mulberry - Morus alba

   The White Mulberry - Morus alba - is a small to medium size tree native to China.  It is recorded to have been widely cultivated in China for over four thousand years to provide feed stock for silkworms. It has been cultivated for Silkworm raising and fruit so much so, that it is hard to determine where the original natural range lines begin/end.  Its leaves are also used as feedstock for livestock in areas where the climate does not allow for adequate ground covers.  It has been naturalized throughout most of the warmer temperate regions of the world including North America, India, and Southern Europe.  In some areas of the United States, it is included on the invasive species list as its ability to hybridize with the native Red Mulberry causes concern for the future of the Red Mulberry species.  If not properly managed this plant has a habit of becoming weedy and invasive, even displacing more desirable vegetation. It is found in hardiness zones 4-9 in North America.  

Image Citation: Stihl Encyclopedia of Trees - R.SPohn

Mulberry fruits are unique because each apparent fruit is actually made up of a cluster of fruits and the fleshy swollen part is the swollen calyx. The fruit is 1–2 1/2 cm long on average.  When found growing wild the fruit is a deep purple, but in many cultivated plants it varies from white to pink. The flavor is sweet but bland, unlike the more intense flavor of the red and black mulberry fruit. The fruit is enjoyed by many wild birds, hogs and poultry.  Seeds are often spread by birds consuming the fruit.  The flowers are single-sex catkins, male and female flowers are usually on separate trees although they may occur on the same tree but usually not connected to one another. The pollen of the White Mulberry has an extremely rapid release, moving at twice the speed of sound.

When young the leaves on the White Mulberry can reach up to 12 inches long, while a more mature tree may only have leaves that are 2-6 inches long.  The leaves are very interestingly shaped and can have as many as five different shaped leaves on one tree.  The leaf shapes vary from a simple ovate to a more intricately lobed version.  During the growing season they are a bright green color changing to a pale to bright yellow in the fall.  In very warm climates the tree may act as an evergreen retaining leaves year-round.  At maturity the White Mulberry reaches an average height of 30-65 feet.

The White Mulberry is said to have some medicinal qualities and has been used throughout history for various ailments.  When taken internally the leaves are said to treat sore throats, eye infections, nose bleeds and the common cold.  The stems have been used in the treatment of rheumatic conditions, high blood pressure and spasms.  The fruit when eaten is said to to help ease dizziness, diabetes and constipation.  The root bark has been used in Asian cultures as a traditional medicine and antibacterial combatant against the micro-organisms that cause food poisoning.

Asian Longhorned Beetle - Anoplophora glabripennis (ALB)

 The Asian Longhorned Beetle - Anoplophora glabripennis (ALB) is a serious pest from China, it has made it's way to the United States and has been observed attacking our trees. This beetle's larvae tunnels into trees, causes girdling of stems and roots, repeated attacks can lead to die back usually beginning with the crown of the tree and eventually the entire tree. It is thought that the Asian Longhorned Beetle traveled to the United States inside solid wood type packaging material from China, it has been intercepted at various ports through the country. Within the United States it appears that this beetle prefers trees in the Maple species (Acer), such as Red, Norway, Silver and Sugar Maples and Box Elders. They have also been found on Birches, Buckeyes, Horse chestnut, Willows and Elms.

The ALB are unique in appearance and quite easy to spot. Adults have a deep black bodies with white spots on the back. They are 3/4 - 1 1/4 inches long and have very long antennae that are usually 1 1/2 - 2 1/2 times the actual length of their bodies. The antennae are clearly marked by white bands or stripes on each segment. The egg laying sites within a trees bark is generally oval or round and are chewed out by the female beetle before she deposits a single egg into each. Some trees- Maples most notably, will ooze sap from the egg laying sites as the larvae feed inside during the summer months. Around the base of infested trees there will be an accumulation of coarse sawdust usually found at the point where the branches meet the trunk, this sawdust is caused from the larvae boring into the tree, stems and branches. When the adult ALB finally exits the tree it leaves a large round hole that is about 3/8 of an inch in diameter on branches or trunks. ALB only have one generation per year and adult beetles are usually only found from July - October. A female can only lay 35- 90 eggs in her entire lifetime and eggs can hatch in 10-15 days. The larvae will live under the bark and continue to feed within the tissues of the tree, they then bore deep into the tree to pupate. The adults emerge from pupation sites by boring tunnels in the wood and creating round exit holes.

Currently in the United States the only way to eliminate the pest is to remove infested trees and destroy them by chipping or burning of the material. There are many quarantines in effect around the country to help prevent further spread of the insect (and other insects). As with most pests early detection is the best defense allowing for rapid treatment/removal, this is the only way the pest can be truly eradicated from an area.

If you suspect that the Asian Longhorned Beetle is in your area it is asked that you collect an adult beetle in a jar and immediately notify officials in your area. You can contact your State Department of Agriculture, Forest Service, State Forester, Department of Natural Resources, or State Entomologist. You can also call toll free to 1(866)-702-9938 .

Solanaceae (Nightshade Family) Tomatoes, Potatoes

 In the family Solanaceae (Nightshade Family) there is a genus called Solanum it contains 1500-2000 varieties of herbs, shrubs and trees. Of these varieties two are major food crops in North America, Potato and Tomato and another less Popular including Eggplant. In other regions there are varieties such as the Ethiopian eggplant, Gilo (S. aethiopicum), Naranjilla or Lulo (S. quitoense), Turkey Berry (S. torvum), Pepino (S. muricatum), Tamarillo and Bush Tomatoes (which includes several Australian species). Most of the members of this family are native to the American Tropics, 65 occur in North America (only 35 are native). Even though two of our largest food crops are included in this genus most of the green parts of the plants and unripened fruits are poisonous, but some bear edible parts in the form of fruit, leaves or tubers. Also included in this genus are Nightshades, Horse Nettles and many other plants cultivated for their ornamental flowers and fruits. The species grows in various habits including annual, perennial, vine, subshrub, shrub and even small trees.

Most of the plants have green simply shape leaves that are ovate or elliptic. Flowers can range in color depending on the variety but generally have 5 petals. The fruits can vary from small and insignificant to large and very visable - berries, tomatoes, potatoes, and eggplants. Some produce fruit from the leaves while other grow underground (like the potato). Many plants in the Solanum genus are an important food source for the larvae of some Lepidoptera species (Butterflies and Moths), these include various Angle shades (Phlogophora meticulosa), various members of the Bedellia species, the Cabbage Moth (Mamestra brassicae), Common swift (Korscheltellus lupulina), Garden dart (Euxoa nigricans), Ghost moth (Hepialus humuli), Tobacco hornworm (Manduca sexta), Tomato hornworm (Manduca quinquemaculata), and Turnip moth (Agrotis segetum) to name a few.

Food Crop production in the Solanum genus is extremely important throughout the world. In 2013, the recorded world production of Tomatoes was 163.4 million tonnes, with China producing 31% of the total, followed by India, the United States and Turkey. In 2012, Tomato production was estimated to be valued at 59 billion dollars, making it the eighth most valuable agricultural product worldwide. In 2013, the recorded world production of Potatoes was 368 million tonnes. Two thirds of the global production is eaten by humans, the remaining third is consumed by animals or used in starch production. Potatoes remains an essential crop in Europe, where per capita production remains the highest in the world. The most rapid expansion over the past few decades has occurred in southern and eastern Asia. As of 2007, China led the world potato production, and nearly a third of the world's potatoes were harvested between China and India. It is believed that the geographic shift in potato production has been moved from wealthier countries toward low income areas of the world because it is a cheap and plentiful crop that is able to grow in wide varieties of climates and locales. Only about 5% of the world's Potato crop are traded internationally because of the perishability. In 2013, the recorded world production of Eggplants was 49.4 million tonnes, 57% of which came from China, 27% from India, Iran, Egypt and Turkey were also major producers all total account for 97% of the world production. More than 4,000,000 acres are devoted to the cultivation of eggplants in the world.

Many members of the Solanaceae:Nightshade family members can be grown in your own landscape some in your vegetable garden and others in you flower gardens. With 1500-2000 varieties and counting I am sure you can find one that is right for you! Hardiness zones vary by plant and within the family can range from zones 4-12.

American Plum - Prunus americana

 American Plum - Prunus americana is best recognized by the combination of flaking scaly bark, sharply toothed leaf margins and red or yellow fruit.  It is a deciduous shrub or small tree that is capable of reaching heights of around 25 feet.  Generally it grows in an erect form with a single trunk, the young shoots are often thorn tipped.

The bark is smooth and reddish brown with horizontal lenticels that becomes tan, buff or grey with age.  The leaves are alternate, simple, elliptical, and oblong with a rounded base.  They are green in color with a hairless upper and lower surfaces, and blades that are 4-12 cm long.  The flower is generally 20-25 mm in diameter with 5 petals.  Generally the flowers are white in color and may become pink with age, they appear in Mid Spring to Early Summer.  The fruit is a rounded or ellipsoid, red, orange, or yellow drupe.  The fruit appears in late summer and is often glaucous with a white waxy blush on the surface.

The American Plum is native throughout the Eastern United States and continuing West through the Rocky Mountain region.  It prefers rich, moist, loamy soils, open woods, woodland margins, fence line and stream banks.  American Plum is sometimes considered to be thicket forming in woodland areas, though it is believed these thickets are formed by seedlings rather than root suckers.  American Plum can be found at most nurseries in the native region.  Currently there are over 260 varieties that have been developed from the American Plum which greatly improve the reach of it's growth range.
