Nyssa sylvatica long stalk and a rich source or nectar for bees. They are often dioecious so a male and female tree in proximity is required to set seed, however, many trees are also polygamo-dioecious, which means they have both male and female flowers on the same tree. The fruit is a black-blue, ovoid stone fruit, about 10 mm long with a thin, oily, bitter-to-sour tasting flesh and very popular with small bird species. There are from one to three fruits together on a long slender stalk. They are a valuable energy food for birds, especially the American robin. "Nyssa sylvatica" forms
