Easily grown in average, medium moisture, well-drained soil. Tolerates filtered sunlight, but prefers full sun. Prefers moist, sandy soils, but has surprisingly good drought and heat tolerance. Wet soil in winter is the main cause of death for this plant. Plants can be cut back to basal foliage after bloom. 
Direct sow outside in fall or early spring.  Indoors start the seeds six to eight weeks before the last spring frost date, barely covering the seeds with soil, since the seeds need light to germinate.
