Malvaceae
Plants in the genus Alcea are native to rocky or grassy wasteland sites in the temperate regions of Europe and Asia. Most are tall and slender biennials or short-lived perennials. Large, brightly colored flowers bloom along the spikes in summer. They look good in mixed borders or along a wall.
Noteworthy characteristics:  Flowers are often double in cultivars. They attract bees and butterflies. Grow as an annual or biennial for best results.
Care:  Moderately fertile, well-drained soil in full sun. Stake in open sites.
Propagation: 

Timing of sowing seed varies if grown as annual or biennial.

Problems: 

Grow as annuals or biennials to limit spread of rust, southern blight, cutworms, slugs, mallow flea and Japanese beetles, and capsid bugs.
