Alcea rosea

Hollyhock, Althea rosea

A classic old-fashioned flower, Hollyhocks are informal, yet elegant. The 5- to 8-foot-tall flower spikes have 3- to 6-inch-wide, saucer-shaped, single, semi-double or double flowers. Butterflies love them. Plant in the back of a flower border or against a wall to show off their strong vertical lines. For smaller gardens, use dwarf varieties that grow 3 to 5 feet tall. Technically biennial, many modern varieties bloom the first year from nursery plants or from seed if started early indoors. Stake tall plants. Protect from strong winds, slugs and snails. The large, hairy leaves are prone to rust, spider mites and anthracnose. They need good air circulation.
