Ecology & Natural History
Habitat: Species is distributed in low woods; upland slopes; bluff tops; rocky woods. ILPIN Notes: Flowers are born from dense clusters of lateral buds; leaves are white or gray and either smooth or hairy on the lower surface; nearly as broad as long; shallow lobes. Wood is moderately heavy, soft, and neither strong nor durable. This pertains to terrestrial furbears (esp. squirrels) who eat seeds, flowers, bark, twigs. Concerning small non-game bird food value, this especially applies to evening grosbeaks. Form - seedlings, whips, balled & burlapped, bare root, seeds. Species may also be monoecious.
