Comes in a variety of colors including purple, peach, orange, violet, yellow, pink, red and white. Blooms resemble pea-like flowers.
Prefers well drained soils but is adaptable to a wide range of soil types. Blooms once in spring and again in fall. Plant in full sun to partial shade and water regularly. Can reach 1-4 feet tall depending on variety. Can winter over but sometimes may not.
For best results, do not prune flowers until after seeds have begun dropping so the plant can grow from seed the following year.
