Clematis viticaulis Steele
The common name, Millboro leather-flower, relates to the location where this species first was discovered, near Millboro in Bath County, Virginia. With a limited distribution in only three Virginia counties, the native range is in Devonian shale and nowhere else. Flowers are described as pale purple with a slight greenish tinge, contrasting the pale greenish white interior. The plant itself looks similar to C. albicoma and C. ochroleuca, with simple foliage and upright stems.
Although the North Carolina Botanic Garden grows this species from seed collected and raised by the Arnold Arboretum, the NCBG refuses to make it available to gardeners or for any commercial purpose.
Identification:A key trait in identification is the copper brown, feathery seed tails, and nearly glabrous sepals.
