Rank Reasons

Robinia viscosa is known from the eastern United States and Europe. The shrub is probably native only to the mountains of western North Carolina and Tennessee, and perhaps southern Virginia, Georgia, and Alabama. It has been introduced elsewhere in the eastern United States and in Europe. It is cultivated and/or established from southern Maine to northern Georgia, and is known from sporadic occurrence westward. Robinia viscosa var. hartwigii is known only from five extant occurrences in North Carolina. The cultivation of Robinia viscosa var. viscosa goes back 175 years and it is now widely established in the northeastern United States.

Range Extent Comments

Known from the eastern United States and introduced in Europe. It is probably native only of mountains of western North Carolina and Tennessee, and perhaps also of adjacent states; cultivated and/or established from southern Maine to northern Georgia, of sporadic occurrence westward (Isely 1998).

Threat Impact Comments

Lack of disturbance leading to succession and uknown causes of decline are moderate threats to this species (Southern Appalachian Species Viability Project 2002). (forest succession is the primary threat to Robinia viscosa var. hartwigii.)

Ecology & Habitat

Habitat

Mountain woodlands, sandy ridges, clearings, ruderal in urban areas (Isely 1998).
