Hollyhock

Alcea rosea

Hollyhock Plant Features

A classic cottage garden favorite, hollyhock produces towers of gorgeous flowers from mid- to late summer. Growing 4 to 6 feet tall, hollyhock is ideal for the back-of-the border or lined up along a fence or building. The single or double flowers can appear in summery shades of pink, red, yellow, black, white, and purple. Hollyhock is a sun lover that thrives during periods of heat and drought. Hummingbirds will also flock to your garden to feast on the nectar-rich flowers. Hollyhock is a short-lived perennial (technically it's a biennial) so add new plants every year to insure a constant flow of flowers. The plants may seed themselves and will take two summers to mature enough to flower. Hollyhock is relatively deer resistant. Hardy from zones 3-8.

Hollyhock Growing Instructions

Plant hollyhock in a location where it receives six to eight hours of direct sun a day. The plants are not fussy about soil type, but do best in a rich, well-drained spot. Stake the plants in windy locations to prevent them from toppling during storms.

Hollyhock is not recommended for human or animal consumption.
