Hollyhock - Alcea Nigra

A novelty selection that is a must have for collectors! Single, deep chocolate-maroon (nearly black!) flowers are produced on tall, strong stalks, opening from the bottom up over a long period in summer. The leaves are deeply lobed in classic alcea form.

Hollyhocks are best treated as a biennial or short-lived perennial.

Hollyhocks provide excellent architectural height in the garden and make good backdrops for lower growing perennials. Try growing them in the cottage garden style by planting them up against a wall of picket fence. Though their stalks are very strong, the may need to be staked if they are planted in a windy site. Hollyhocks prefer rich, moist, well-drained soil but can tolerate short periods of drought. They need full sun to really perform in the landscape.
