Family

Malvaceae

Botanical Name

ALCEA rosea

Plant Common Name

Hollyhock

General Description

Hollyhock is a tall, short-lived, herbaceous perennial native to western Asia. In summer, large rosettes of characteristically rough, hairy leaves give rise to very tall, leafy stalks lined with show-stopping flowers of rose-pink. Single, semi-double and double-flowered varieties are also available in a wide array of colors to include dark purple, red, white, apricot and yellow.

All hollyhocks are highly attractive to butterflies and bees and thrive in full sun and moderately fertile soil with good drainage. This old-fashioned flower makes an excellent addition to cottage gardens and mixed borders. Plants often require staking, and are highly susceptible to powdery mildew and Japanese beetle predation.
