How to Grow

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.

Propagation: Sow seed in early spring in a warm greenhouse; germination is usually fairly rapid. Prick seedlings into individual pots when large enough to handle. For annual cultivation, plant out in early summer with frame or cloche protection until established. For perennial cultivation, grow on in the greenhouse for the first year and plant out in early summer of the following year. Half-ripe cuttings taken in July or August can be rooted in a frame, overwintered in a warm greenhouse, and planted out after the last expected frosts.

Medicinal Uses

The flowers are diuretic and are used in the treatment of itch and painful skin diseases. The dried leaves are regarded as stomachic.

Other Uses

The nectar- and pollen-rich flowers attract bees and butterflies. The plant provides some food and habitat for wildlife through its edible calyces and foliage, and can support beneficial insects through its leaf litter, though it is not a primary bird nesting site. The plant is not known for pest-deterrent properties.

Hibiscus trionum, commonly called flower-of-an-hour, bladder hibiscus, bladder ketmia, bladder weed, puarangi and venice mallow, is an annual plant native to the Old World tropics and subtropics. 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.
