This is a species of open woodland, very local and apparently declining in the northern portions of its range.
The status of this species in Michigan is uncertain. Despite other reports from the state, the only Michigan collection seen was made by O. A. Farwell at Detroit, Wayne Co. in 1917 (BLH). This occurrence is substantially out of range, and since he collected many cultivated plants the same day, it could be that this was not a native occurrence.
Plants are dioecious and somewhat dimorphic. Male plants in bloom have a long staminate inflorecence, bottlebrush-like with spreading anthers and quite showy. Female plants have a more compact and shorter inflorescence, though elongating in fruit.
