|Lavatera thuringiaca is a perennial with mid-green leaves. Grown for their showy, open, funnel-shaped pure white summer flowers, 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. Also known as L. Peppermint Ice.
