How to Grow
Succeeds in semi shade and full sun. Grows wild on sandy seashores, moist clay, rarely on salt flats. Plants can be in flower in all months of the year.
Propagation: Seed. The seed of wild rice less than 12 months old often exhibits strong dormancy, which implies (though this has not been established) that the seed retains its viability for a considerable period. Heat treatment is generally effective in breaking dormancy - alternating temperatures between 34°c for 16 hours then 11°c for 8 hours is usually effective, though the time taken varies between species. Surface sow the seed in light shade and do not allow to dry out. Seed should germinate within 7 days at 30°c. Prick out 2 - 3 seedlings into individual pots when large enough to handle and, after a few days, move to a sunny position. Grow on until large enough to plant out.
Other Uses
The cortex/epidermis is used to cut hair. Because they are a source of resistance to or tolerance of biotic and abiotic stresses, the most important use of the various species of wild rice is probably in breeding programmes to improve the species of cultivated rice.
