Identifying Characteristics: Ability to grow successfully on sites with very different moisture availability is due in part to the early development of roots specifically adapted to the conditions at a particular site.

Flower Seed Head: Noticeable long before the foliage emerges. They have small fragrant red flowers in dense clusters in late winter to early spring.

Seed Fruit: Seed is a paired, red, pink, or yellow, winged samara, about long. Fruits are winged with a single seed at the base.
