Flower and Fruit Details
Flowers are slightly fragrant, greenish-yellow, 6 petals 2.5-3" long, slightly fragrant, May-early June. Some are self-fertile but most are not. Born solitarily and are often high in the tree, masked by the foliage. Fruits are aggregates of follicles, pinkish-red, in October persisting briefly, 2-3" long. They look somewhat like a small cucumber.

Suggested Uses
An excellent tree for a large property or a park.
