: Hibiscus trionum
Habitat : Hibiscus trionum is native to the Levant. It has spread throughout southern Europe both as a weed and cultivated as a garden plant. It has been introduced to the United States as an ornamental where it has become naturalized as a weed of cropland and vacant land, particularly on disturbed ground.
Hibiscus trionum is an annual/perennial plant.It grows to a height of 20–50 centimetres (7.9–19.7 in), sometimes exceeding 80 centimetres (31 in), and has white or yellow flowers with a purple centre. In the deeply pigmented centre of the flower, the surface features striations, which were previously considered to act as a diffraction grating, creating iridescence. Because of the irregularities of the plant cells and surface, the periodicity of the striations is however too irregular to create clear iridescence and thus the iridescence is not visible to man and flower visiting insects. The visual signal of the flower’s of H. trionum to flower visiting insects is thus determined by the white and red pigmentary coloration. The pollinated but unripe seedpods look like oriental paper lanterns, less than an inch across, pale green with purple highlights.
The flowers of the Hibiscus trionum can set seed via both outcrossing and self-pollination. During the first few hours after anthesis, the style and stigma are erect and receptive to receive pollen from other plants. In the absence of pollen donation, the style bends and makes contact with the anthers of the same flower, inducing self-pollination. Although outcrossing plants seem to perform better than self-pollinating plants, this form of reproductive assurance might have contributed to the success of H. trionum plants in several environments.
Prefers a well-drained humus rich fertile soil in a sheltered position in full sun A very ornamental plant, it is an annual or short-lived perennial. Not very frost-tolerant, if started off early in a warm greenhouse it can be grown as an annual in Britain, flowering and setting seed in its first year.
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.
Edible Uses: Young leaves and young shoots – raw or cooked. Root – it is edible but very fibrousy. Mucilaginous, without very much flavour.
Diuretic; Skin; Stomachic.
The flowers are diuretic. They are used in the treatment of itch and painful skin diseases. The dried leaves are said to be stomachic
