Abelmoschus moschatus is a perennial herb or 2 m tall shrub that occurs across coastal areas of northern Australia and along the east coast to South Stradbroke Island. There are two recognised subspecies. Subsp. moschatus is native to India, southern China, tropical Asia and some parts of the Pacific but there are naturalised occurrences in northern New South Wales. Subsp. tuberosus occurs in South-east Asia and northern Australia and is regarded as a possible early introduction to Australia [13, 43]. In Australia, subsp. tuberosus grows in seasonally wet areas or near creeks, in open forest and woodland, in a wide range of soils from sands to heavy clays. It is regarded as weedy outside of its natural habitats and will colonise in disturbed and cultivated areas .
Flowering and seeds
Subsp. tuberosus flowers spring to autumn. Flowers last for one day only but are very prolific and flowering time depends on the timing of the wet season . Fruiting in autumn; the seeds are musk scented. Propagation may be from seeds, small tubers or stem cuttings. Seeds germinate readily but some difficulty is often experienced in getting the plant to establish in the ground . A perennial plant, the foliage dies back in the dry season to grow again from its tuber during the wet season.
Cultivation and uses
Leaves, shoots and tuberous roots can be eaten raw or cooked and were a source of food for Aborigines [36, 110]. An emulsion made from the seeds of this plant is considered to be a breath sweetener, an insecticide and when mixed with milk, the emulsion relieves itching . In cultivation, two varieties are recognised with the flower with the white or yellow with a red or maroon centre (common form in the Northern Territory) or deep pink to red (common form in Queensland) .
