|Lavatera arborea, depending on the culitvar, may be either a perennial, annual, or biennial. Grown for their showy, 2 to 7 petaled, funnel-shaped, purple-pink summer flowers, the mallow does best when grown in light soil that is moderately fertile and well-drained. The leaves have distinctive white markings and fade to green when it gets warm. Sun should be full. Will not tolerate cold, drying winds. For annuals, sow in situ, mid to late spring, biennials in midsummer.
