Propagation of Oxystigma gilbertii J.Léonard
Oxystigma gilbertii J.Léonard, commonly known as "Koki'o ke'oke'o," is a rare Hawaiian flowering plant. Propagation of this plant can be done through various methods, such as seeds, cuttings, and layering.
Propagation through seeds
The best time to collect seeds of Oxystigma gilbertii J.Léonard is during the months of May and June. The collected seeds should be moistened and stored in a shaded area until they split, indicating germination. Once the seeds have germinated, they should be transplanted into individual containers and kept in a humid environment until they have reached a suitable size for transplanting.
Propagation through cuttings
Cuttings can be taken from mature plants of Oxystigma gilbertii J.Léonard. The cuttings should be approximately six inches long and taken from the tips of healthy, non-flowering stems.
