More about this plant

It is now currently known only from small populations in Davidson and Obion County, Tennessee. This species has been taken into cultivation. It forms a vigorous shrub to 8 m in height with hairy leaves, attractive flowers and round reddish fruit. Wikipedia →

❧ Caterpillar hosts ~168 caterpillar species

Crataegus supports ~168 caterpillar species.

Native butterfly & moth caterpillars are the base of the terrestrial food web — most songbirds rear their young almost entirely on them. As a host for native Lepidoptera this is an exceptional genus.
