Propagating through Seeds
The most common method of propagating Brillantaisia didynama Lindau is through seeds. The seeds should be collected from the plant when the pods are dry but have not yet opened. It is important to sow the seeds immediately in seed trays filled with a suitable soil mixture. The trays should be watered regularly and kept in a warm, well-lit area. Germination usually occurs within two to four weeks. Once the seedlings have several leaves, they can be transplanted into larger containers or directly into the ground.
Propagating through Cuttings
Brillantaisia didynama Lindau can also be propagated through stem cuttings. Select sturdy, healthy stems and make a clean cut just below a node.
