The "Eastern Hemlock" - Tsuga Canadensis

The "Eastern Hemlock" - Tsuga Canadensis is a very unique evergreen/conifer, this is because it's terminal leader often droops instead of giving the tree a typical pointed top like most in the Pine family. It's natural range begins to the North in Nova Scotia and continues South through Wisconsin and Minnesota, throughout the Alleghany Mountains and South through Georgia and Alabama. It is native to every state along the East Coast with the exception of only Florida in the far South. It is very common in the Mountains of Pennsylvania and Ohio, it is the only Hemlock variety that is native to Ohio. It's hardiness zone is 4-7. In the Southern range it is found only where there is moist air, rocky ridges, valleys, ravines lakeshores and hillsides. In the Northern range it is found in a wider variety of locations including on low rolling hills and even glacial ridges. It most commonly grows in mixed stand settings along with White Pine, Red Oak, Sugar Maple, American Beech, White Ash, and Yellow Birch.

In Eastern North America the Eastern & Carolina Hemlocks are greatly threatened by the Hemlock Woolly Adelgid. Trees infested with Hemlock Woolly Adelgid can be easily identified by visable egg sacs, which resemble small tufts of cotton clinging to the underside of hemlock branches. Once infested trees generally become a grayish-green instead of there rich healthy green color. This pest feeds on the phloem sap of tender hemlock shoots, and may also inject a toxin while feeding. The resulting desiccation causes the tree to lose needles and not produce new growth. In the northern portion of the Hemlock's range, death typically occurs four to ten years after the initial infestation. Trees that survive the direct effects of the infection are usually weakened and may die from secondary causes. This pest has been identified as active in 11 states within the Hemlocks growth range causing major concern for the future of these majestic trees.

The Eastern Hemlock does not begin to produce cones until about the age of 15. The brown cones are relatively small only 1/2-1 inch in length and usually not more then a 1/2 inch wide. Once the cones begin production they come in high volume and for many many years, some specimen have been found producing cones even at 450+ years old. Seed viability is generally low, even though there are a large number of cones produced. The Hemlocks seed is easily damaged by drying. They regenerate best on exposed decomposing layers under 70-80% crown cover, in rotten logs or stumps or mounds where the temperature is warmest among the forest floor.

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

The Eastern Hemlock grows in an upright primarily conical fashion with long branches that often droop at the ends. At full maturity they can average 100 feet tall but have been found growing as tall as 170+ feet. The bark is brown, scaly and fissured . The bark was once used commonly as a source of tannin or the leather industry. The needles are evergreen and flat, usually 5-25 mm long and set on each branch with peg like projection.

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

The wood is not of a high enough quality furniture making. It is used for light framing material, boxes, crates and even pulping. It is not considered an important timber tree in today's market. Commercial stands have been greatly reduced by prior harvesting and lack of replanting.

The Eastern Hemlock can be used as a specimen tree, planted in groups for screening, or even trained/sheared over time into formal evergreen hedgerows. It is tolerant of full shade and has a natural open growth habit.

The "Southern Magnolia" - Magnolia grandiflora

The "Southern Magnolia" - Magnolia grandiflora - is a medium sized evergreen tree.  It is also called the Bull Bay, Big Laurel, Evergreen Magnolia or Large Flower Magnolia.  The native range of the Southern Magnolia goes from North Carolina south down the Atlantic Coast and through Georgia, Alabama, Mississippi, Louisiana, and Central Texas.  Averaging 60-80 feet tall in ideal locations, they usually reach maturity at 80-120 years.  It typically grows in an oval pyramidal shape.

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

Featuring leathery leaves 5–10" in length, with a lustrous dark green top and soft, rusty underside.  The large White fragrant flowers appear April-June and are almost perfect in form.  The fleshy cone shaped fruit mature in late fall.  The fruit are 5-8 inches long and attract a wide range of wildlife including Squirrels, Rabbits and Birds. 

Image Citation (Photo 3): Franklin Bonner, USFS (ret.), Bugwood.org

Recommended for zones 6-10 this variety can be grown as far North as Maine and is found planted over most of the country with the exception of the North-Central Region.   Air-layering, stem cuttings and grafting are all sucessful means of propagation.  It can be found at most nurseries in it's growth range.  It is best planted as a landscape tree versus a street tree as the leaf, flower and fruit debris are often considered messy.  

The name Magnolia honors French Botanist Pierre Magnol, who was so impressed with the tree he transplanted one near his home in Europe over 300 years ago.  One of these trees grows on the White House grounds, it was transplanted by President Andrew Jackson from his home in Nashville, Tennessee.  This tree was transplanted to honor his late wife Rachel's memory.

The 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 rockland 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.
Image Citation: Forest and Kim Starr, Starr Environmental, Bugwood.org

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.


Image Citation: Forest and Kim Starr, Starr Environmental, Bugwood.org

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).

The 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.

The American Beech - Fagus grandifolia

The American Beech - Fagus grandifolia can be most easily identified by the combination of smooth gray to almost blue gray bark, coarsely toothed leaves and elongated torpedo shaped buds. It is a deciduous tree that can reach heights of near 100 feet if given the right location and ideal growing conditions. Generally growing in an erect upright fashion with a single main trunk and broad open crown. Native to rich woodlands, moist slopes and deciduous forests the American Beech can be found growing from New Brunswick and Ontario in the North South through Texas and Florida between 0-1250 m. It is believed that the best specimens are found growing in the Ohio and Mississippi River Valleys where growing conditions are ideal.

Image Citation (Close up of Leaves): Rob Routledge, Sault College, Bugwood.org

Even without leaves the bark of the American Beech sets it aside and makes it easy to identify, smooth in texture and gray to almost blue gray in color it is a stark contrast to the Oak and Pines generally found growing nearby. With age this smooth bark tends to darken and develop cankers or molten in appearance. The leaves are equally interesting, simply shaped ovate or elliptic they are coarsely toothed on the edges. The upper leaf surface is lustrous and dark green in color, while the lower surface is paler and hairy. In the fall the leaves begin to shift from green to yellow, then a lustrous brown and finally a pale brown before falling and making room for new leaves in the Spring. The flowers are tiny, the males are borne in a globular head at the end of a silky stalk, the female are inconspicuous borne singly or in pairs. The fruit is a bristly 4 compartment cupule that usually contains 2 angled or ridged nuts (occasionally 1 or 3).

Image Citation (Fall Foliage):T. Davis Sydnor, The Ohio State University, Bugwood.org

The American Beech is readily available at most nurseries within hardiness zones 4-9, it is a slow grower and can be planted as both a shade tree and an ornamental. Full sun is ideal for the American Beech - meaning it should get at least six hours of direct, unfiltered sunlight each day. Be sure when planted that there is ample space available as when full grown the American Beech can reach heights of 100 feet tall with a spread of 40-50 feet. Beechnuts are frequently eaten by birds and small mammals, they serve as an important food for both chipmunks and squirrels.
