Alcea rosea is variously described as a biennial (having a two-year life cycle), as an annual, or as a short-lived perennial.
It frequently self-sows, which may create a perception that the plants are perennial. The plant may flower during its first year when sown early. It will grow in a wide range of soils, and can easily reach a height of about 2,50 m.
The flowers are full, dark red. This variety likes sandy soils, while the lighter colour seems to favour clay soils.
Succeeds in almost any soil and situation, though it prefers a rich moist soil in a sunny position. It also tolerates fairly dry soil conditions. Plants are hardy to about -25°c. Marsh mallow is often cultivated in the herb garden, as a culinary and medicinal herb as well as for ornament. Its roots were at one time the source of the sweet 'marsh mallow', but this sweet is now made without using the plant.
