The seeds are formed inside quite large 3-winged capsules, which turn brown and dry as the seed matures. The seed capsule splits open at the top to release the ripe seeds that are light brown, hard and flat. The best time to sow is in autumn, which is the start of the rainy season in the Cape. The seeds are sown in seed trays filled with a well-drained potting soil. After sowing, the seeds are lightly covered with milled bark or white sand, watered well and placed in the shade.
Germination is usually very good and within a month.
The young plants only start to flower after about 3 years. Mature plants can be transplanted and divided after flowering, but this should only be done if really necessary. Lift the clumps with care and make sure that the rhizomes do not dry out. The plants should not be out of the ground for long. Keep the ground moist till the plants are established.
