Althaea

Article about the genus Althaea

Althaea is a genus of perennial herbs in the family Malvaceae, native to Europe and western Asia. The genus includes several species, the most well-known being Althaea officinalis, commonly known as marshmallow.

Description

Plants in the genus Althaea are characterized by their tall, erect stems, which can reach heights of up to 2 meters. The leaves are palmately lobed, and the flowers are typically pink or white, with five petals. The flowers are borne in clusters and are known for their soft, velvety texture.

Species

The genus Althaea includes several species, among which the most notable are:

• Althaea officinalis – Marshmallow
• Althaea hirsuta – Hairy marshmallow
• Althaea armeniaca – Armenian marshmallow

Uses

The most famous species, Althaea officinalis, has been used for centuries in traditional medicine. The roots of the marshmallow plant contain mucilage, which has soothing properties and has been used to treat sore throats and other irritations. The plant has also been used in the production of the confectionery known as marshmallow, although modern marshmallows are typically made without the plant.

Cultivation

Althaea species prefer moist, well-drained soils and can be grown in full sun to partial shade. They are hardy plants that can tolerate a range of soil types, but they thrive in rich, loamy soils. Propagation is typically done by seed, although division of the rootstock is also possible.

Ecology

Althaea plants are important for pollinators, attracting bees and other insects with their nectar-rich flowers. They are also used as larval host plants by some species of butterflies and moths.
