Alcea (Hollyhock)
Genus of about 60 species of biennials and short lived perennials found in temperate regions of Europe and Asia, usually in rocky sites and on dry grassy wasteland. Suitable for a mixed border or along a fence or wall. Attractive to butterflies and bees.
CULTIVATION: Grow in moderately fertile, well drained soil in full sun. May require staking in exposed sites. Grow as annual or biennials to limit the spread of hollyhock rust.
PROPAGATION: To grow as annuals, sow seeds at 55 degrees F (13 degrees C) in later winter. For biennials and perennials, sow seed i situ in midsummer. If required, transplant in early autumn, when 2 or 3 true leaves have developed.
PESTS AND DISEASES: Susceptible to hollyhock rust as well as bacterial and fungal leaf spots. Southern blight is quite common. Cutworms and slugs may damage young growth. Mallow flea beetles, aphids, Japanese beetles, and capsid bugs are sometimes a problem.
