Hibiscus mutabilis (common name: cotton rose)

Propagation: Seed - sow early spring in a warm greenhouse. Germination is usually fairly rapid. Prick out the seedlings into individual pots when they are large enough to handle. If growing them as annuals, plant them out into their permanent positions in early summer and protect them with a frame or cloche until they are growing away well. If hoping to grow them as perennials, then it is better to grow them on in the greenhouse for their first year and to plant them out in early summer of the following year.

Cuttings of half-ripe wood, July/August in a frame. Overwinter them in a warm greenhouse and plant out after the last expected frosts.

Cultivation: Prefers a well-drained humus rich fertile soil in full sun[1]. Prefers a warm but wet winter[2].

This species is not very hardy in Britain, it is frost-tender and top growth will be killed by even a slight frost. However, the roots are somewhat hardier and the plant can resprout from the base after a few degrees of frost[1][2]. The plant can probably be grown outdoors in the mildest areas of the country especially if given a good mulch in the winter. It is widely cultivated in tropical and occasionally in temperate areas as an ornamental plant, there are many named varieties[1].

Range: E. Asia - China, Japan.

Habitat: Thickets in S. Japan[3].

Edibility: Leaves[4]. The leaves contain rutin, but the report does not say what quantity[5].

Root - it is edible but very fibrousy[6]. Mucilaginous, without very much flavour[6].

Medicinal: The leaves are anodyne, antidotal, demulcent, expectorant and refrigerant[5]. With the flowers, they are applied to burns, swellings and other skin problems[7][5][8].

The flowers are antiphlogistic, depurative, febrifuge, pulmonary and stimulant[7][8]. A decoction is used in the treatment of lung ailments[5][8].

Usage: A fibre from the bark is used for making cords and rope[9][10].

Pollinators: Insects

Soil: Can grow in light, medium, and heavy soils.

Drainage: Prefers well drained soil.

Seed Ripens: Early Fall-Late Fall

Flower Type: Hermaphrodite
