Blackgum

Nyssa sylvatica
This native tree is also called a tupelo, which is a combination of Creek Native American words  meaning tree and swamp.  As that name implies, it can grow well in wet lands but also tolerates other soil conditions. It prefers full to partial sun, and heights range from 40-80 ft. Some special characteristics about this tree are its glossy green leaves in the summer which turn a brilliant, red purple in early fall.  In the mature trees the trunk bark is grooved and furrowed taking on the appearance of alligator hide. The spring green-white flowers evolve into clusters of sour black-blue fruit, hence another common name for this tree, sour gum.  The fruit is great food for birds, particularly the American Robin. The wood is heavy and difficult to split which makes it useful for making pulleys, wheel hubs and pallets. Here is a possible Glendale connection: The wood is very resistant to wear and absorbs creosote base preservatives.  For these reasons it is one of the best woods for the production of railroad ties.
