Propagation by Seeds
The seeds of Hormogyne altissima A.Chev. should be collected when the fruits have turned brown and the seeds have dried out. They should then be stored in a cool, dry place before sowing. Before sowing, the seeds should be scarified to break their hard outer coats and improve their germination rate. This can be done by nicking the seed coat with a knife or rubbing the seeds with sandpaper.
The seeds should be sown in a seed-raising mix and kept moist. The ideal temperature for germination is between 20-25°C. Germination can take anywhere from 2-8 weeks, but may take longer depending on environmental conditions.
Propagation by Cuttings
Hormogyne altissima A.Chev. can also be propagated by cuttings. Semi-hardwood stem cuttings taken from the current season's growth are the best for propagation.
Using a sharp, clean knife, make a clean cut through a stem just below a node. Remove 3-4 leaves from the lower end of the cutting. Dip the cut end into rooting hormone powder and insert it into a pot filled with a well-draining propagation mix. The cutting should be watered and covered with a plastic bag to maintain humidity.
The pot should be kept in a warm, brightly lit area but out of direct sunlight. After a few weeks, roots should start to develop. Once the roots have become well-established, the plant can be transplanted into its permanent pot or garden location.
