How to growType: perennial
Rose mallows grow in Zones 4-9. They do best in full sun but will tolerate light shade. Soil should be moist and well-composted. Space plants about 3 feet apart. When setting out plants place the crowns, or tops of the root structures, 3 to 4 inches beneath the soil. To start new plants from seeds, sow early in spring; the new plants will produce only a few flowers the first year, but will come into full bloom in subsequent years. Because the rose mallow clumps do not spread underground, the plants can be allowed to remain undisturbed indefinitely.
