Rose-mallow is a vigorous perennial that produces enormous dinner-plate blooms in summer and thrives in moist to average soils with part to full sun. It dies back to the ground in winter but re-emerges reliably in spring, so mark its location to avoid accidental disturbance. Feed with a balanced slow-release fertilizer in spring to fuel its fast growth and prolific flowering.
