About

Althaea is a genus of herbaceous perennial plants native to Europe, North Africa and western Asia. It includes Althaea officinalis, also known as the marshmallow plant, whence the fluffy confection got its name. They are found on the banks of rivers and in salt marshes, preferring moist, sandy soils. The stems grow to 1–2 m tall, and flower in mid summer. The leaves are palmately lobed with 3–7 lobes. Althaea species are used as food plants by the larvae of some Lepidoptera species including Bucculatrix quadrigemina.

Uses

The traditional medicinal uses of the plant are reflected in the name of the genus, which comes from the Greek althainein, meaning "to heal".
