These wonderful shrubs have arching pea foliage and flower in late summer.
If pruned hard they will re-grow from the base. Grow them all in a dry sunny spot.
The Campylotropis makes a much denser shrub and would be ideal at the front of a border or hanging over a raised bed.
The Lespedezas will grow taller, probably reaching 5 -6'. They will need support or another plant to grow through.
