10 Seeds Althaea cannabina Palm-Leaved Marsh Mallow Hardy Perennial Flower

Althaea cannabina, commonly called palm-leaved marsh mallow, is a hardy herbaceous perennial grown for its airy sprays of pale pink, five-petaled blooms that appear through summer into early autumn. Its finely divided, palm-like foliage forms an upright, bushy clump that brings a light, natural texture to borders, meadow plantings, and cottage-style gardens.
This undemanding species suits the middle or back of a sunny border and combines well with grasses and other late-season perennials. The open blooms are visited by bees and other pollinators, and the tall stems can be left standing for winter interest. It performs best in a well-drained site and, once established, tolerates periods of dry soil.
