The Ouachita Mountain indigo is a small attractive shrub that grows to approximately 2 meters in height. The leaves are pinnately compound with broadly elliptical leaflets. The plant blooms from late April to early June. Individual flowers are tiny, but cluster together in the inflorescence, where the royal purple petals and gold anthers make a truly stunning display.
Distribution & Occurrence
In clearings in woods on rocky hillsides, immediately adjacent to streams, near rocky creeks, stream banks, and flood plains.
Amorpha ouachitensis is found growing in association with Calamovilfa arcuata (also a rare plant), Streptanthus squamiformis, and Guara demareei.
|Currently known from at least eleven populations in eight counties in Arkansas and three counties (McCurtain, Leflore, Pushmataha) in Oklahoma (Oklahoma Natural Heritage Inventory 1999).|
