Description

Biennial or short-lived perennial that is winter hardy to USDA Zones 3-7. It is easily grown in average, medium moisture, well-drained soils in full sun. Best in moist, organically rich soils. Tolerates heat, drought and a wide range of soils except poorly-drained wet ones. Deadhead spent flowers to encourage additional bloom and/or to prevent any unwanted self-seeding. Whether or not plants survive from one year to the next, they freely self-seed and will usually remain in the garden through self-seeding.
