Description

Selection of an Arkansas native from Dr. Allan Armitage's trials at the University of Georgia. It has lovely fine foliage like Amsonia hubrichtii and is a compact, well-branched and vigorous plant. In late summer it is covered with true purple flowers that attract plenty of butterflies. Found in rocky flood plains, Vernonia lettermanii is very tolerant of hot dry locations, yet can withstand brief periods of inundation.
