Set plants 12 inches apart. Choose a sunny location where the soil is well drained and on the light side. Plants will also tolerate light shade but bloom will not be as profuse. Cover the crowns with 1 inch of soil.
Plants may be divided as they become overcrowded. Remove flower stems once blooms have finished. In cooler regions where snow cover is not dependable, we recommend a winter mulch.
