Plant notes
Bell-shaped pink to lavender flowers bloom in clusters on upright stalks. Flowers look like elongated snapdragons, but are closed. This plant remains green throughout the summer and bloomed from late May to mid-June. This was the fifth most attractive early season plant to natural enemies, with slightly more natural enemies than the grass control.
Habitat
This plant tolerates full to partial shade and average to dry moisture conditions. It naturally occurs on open, sandy, usually dry ground, in fields, roadsides, prairies, streams and riverbanks, and rocky ground.
Cultivation and management
Sown seed flowers in second or third year. It can also be grown from plug material (flowers in first or second year).
