The Butternut - Juglans cinerea, is a medium to large sized deciduous tree that can reach heights upwards of 75 feet in ideal growth conditions. It is sometimes also referred to as the White Walnut and is best recognized because of it's combination of long pinnate leaves with multiple leaflets and sticky 4-angled fruit husk. It is native to the woodlands, floodplains, river terraces, and rocky slopes of the Eastern United States. Found from New Brunswick, West through Minnesota in the North continuing South to South Carolina, Georgia, Northern Alabama, Northern Mississippi and Arkansas. It is sometimes confused with the Black Walnut (Juglans nigra) but the fruit husks are greatly different as one has ridges and the other lacks ridges and angles all together. This species is considered to be at risk as the Butternut Canker a fungal disease caused by Sirococcus clavigignenti-juglans-dacearun, has wiped out large populations throughout the native growth range.

The Oakleaf Holly - Ilex x conal is most easily identified by its leaves that are similar in shape to an Oak tree. Recommened for USDA Hardiness Zones 6-8, it can reach heights of 15-20 ft tall and 10-15 ft wide. It prefers full sun and moist, well drained soil that is slightly acidic. The foliage is Emerald Green in color but fades to a lighter coppery green during the winter.

As with most other Hollies, The Oakleaf Holly can serve well as a yard hedge, formally or informal, as a singular focal point or to anchor a corner. The Oakleaf Holly is one that I have in my own backyard (7) of them to be exact. We planted ours around our deck to anchor the corners where the stairs meet the deck and then have one in a corner to hide our crawlspace access. Heavy pruning is not required on the Oakleaf Holly as it naturally maintains a somewhat pyramid form. More pruning will be required if you are attempting to train this variety to grow into hedge form or have a "perfect" shape (less natural appearance).

Oakleaf Holly can be found at most larger Nurseries within Hardiness Zones 6-8. We found ours from a local nursery/grower near Dover, Delaware (balled and burlapped). I have yet to see any available at the smaller garden centers or large chain stores in my area.

It is that time of year again where those mysterious little tents seem to form in our trees overnight. Have you ever wondered what they are and what they are doing in there?

In the quaint village of Nashville, Indiana near the Brown County State Park lies the Yellowwood State Forest. The Yellowwood State forest was organized in 1940 when federal lands were leased to the state of Indiana, this land was eventually deeded to the state in 1956. Over the years more then 2000 acres of abandoned and eroded lands within the Parks footprint have been planted with various Pines (jack, red, shortleaf, white and scotch), Black Locust, Black Walnut, White and Red Oaks. The Yellowwood Lake which covers 133 acres and is 30 feet deep at it's deepest point was completed in 1939, there are two other lakes within the park though much smaller in size (Bear Lake and Crooked Creek Lake). Over the years the Yellowwood State Forest has increased in size by gaining parcels of land through the Heritage Trust Program. Their are many activities to enjoy while visiting the Park including Fishing (a boat launch is located in the South end of the main lake), Hunting (Whitetail Deer, Ruffed Grouse, Turkey, Squirrel, Fox, Woodcock and Raccoon-valid Indiana Hunting license required), Primitive Camping, Horsemen's Camping (many miles of horse trails within the park), Gold Panning (must have permit), Hiking, Kayak/Canoe Rental and Picnicking. Today the Forest covers 23,326 acres, made up of 17 different areas all located within Brown County.

The Gray Birch - Betula populifolia Marshall, is most easily distinguished by it's triangular leaf with flattened base, elongated tip and doubly toothed margins. It is a deciduous tree that reached heights of about 40 feet. Generally growing in a multi trunk, curving or leaning fashion it makes for a beautiful focal point in both residential and commercial landscape settings.

The "Tree Circus" originally opened in 1947, as a roadside attraction in Scott's Valley California. Axel Erlandson a bean farmer who pruned, grafted and trained the trees into various shapes as a hobby to amuse himself and his family, went to his grave holding the secrets of his technique. Most of his work was performed behind screens to protect his secret methods from the potential spy! Since his death in 1964 many have tried to recreate his work unsucessfully, so this method of privacy seems to have paid off. Sadly now it seems this type of tree "training" talent may never be seen again.

Sudden Oak Death (Phytophthora ramorum) - SOD (also known as Phytophthora canker disease), was originally identified in Germany and The Netherlands in the early 1990's on Rhododendrons . Since being discovered in the United States, it has been confirmed in forests from California, Oregon, Washington and British Columbia. The origin geographically of Phytophthora ramorum is unknown and before the early 1990's there were no reports in Europe or the United States. The areas that do exist in Europe and the United States are believe to have been originally transported from other areas or even the original site of origin. Phytophthora ramorum's very limited distribution related to the host's distribution suggests a more recent introduction versus a point of origin.

Though it is thought to be a beautiful plant by many (myself included), English Ivy- Hedera helix is a very invasive plant in our area and can cause severe damage to properties and even death to the trees it grows on without proper management. English Ivy vines quickly and easily take over areas that are cleared/disturbed, woods lines, brick work, trellises, garden areas, and even tree trunks / canopies. Ivy can decimate the natural ecosystem by girdling out mature trees and other plantings and overtaking native ground coverings. It is native to Europe, Western Asia and Northern Africa and was introduced to the United States by European immigrants. Common uses as an ornamental vine, landscape buffer, ground cover and climbing vine have all made English Ivy very popular. Over the past couple decades English Ivy has spread from a simple ornamental vine to a naturalized (and very invasive) vine in 18 of The Unites States including Maryland
