Hermannia filifolia L.f. var. passerinoides Harv. can be propagated by seed or vegetative means.
Propagation by Seed
Seeds of Hermannia filifolia L.f. var. passerinoides Harv. can be collected from mature fruits. Fruits are often retained on the plants until the following season. Collect the ripe fruits and allow them to dry out for a few days. Once dry, break open the fruits to reveal the seeds. Sow the seeds in a well-draining seed-raising mix to a depth of 1-2 mm. Keep the mix moist and ensure the pots are kept in a warm, sheltered position. Germination occurs within 2-4 weeks. Transplant the young seedlings into individual pots once they have several true leaves.
Propagation by Vegetative Means
Hermannia filifolia L.f. var. passerinoides Harv. can be propagated by taking softwood or semi-hardwood cuttings. Softwood cuttings are best taken during spring or early summer when new growth is present. Semi-hardwood cuttings can be taken during late summer to early autumn. Ensure the parent plant is in good health and free from pests and diseases. Select a shoot with several nodes and remove all leaves except for the top few. Dip the base of the cutting into rooting hormone powder and insert it into a well-draining potting mix. Water the cutting and cover with a plastic bag to retain moisture. Place the pot in a warm, bright position but out of direct sunlight. Once roots have formed, gradually acclimate the cutting to outdoor conditions before transplanting into a larger pot or into the garden.
