|Lavatera trimestris is an annual with 3 to 7 lobed, mid to deep green leaves. Grown for their showy, open, funnel-shaped, bright rose-pink summer flowers, 5 inches in width, with dark veining and produced singly from the axils. 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.
