|Lavatera, depending on the species, may be either a perennial, annual, or biennial. Grown for their showy, 5 petaled, funnel-shaped deep cerise-pink summer flowers with darker veining, the mallow does best when grown in light soil that is moderately fertile and well-drained. Sun should be full. Will not tolerate cold, drying winds. For annuals, sow in situ, mid to late spring, biennials in midsummer.
