Propagating Staavia radiata from seed and cuttings is challenging.

Seed collection is difficult because the seeds are very small and the flowers are everlasting, thus, one does not know whether the seeds are ripe and ready, or have already been shed or are underripe and not available. But once seeds are collected, and sown in autumn, germination occurs after 2 to 3 weeks. Seeds are treated with smoke from burning fynbos before being sown; this breaks the seed dormancy and increases the percentage of seeds that germinate.

Rooting Staavia radiata cuttings from any part of the vegetative growth is difficult. Cuttings which root better are heel cuttings taken from resprouting vegetative growth after a fire. A root stimulating hormone, such as auxin powder or IBA, is used to propagate 50–70 mm long cuttings. Visible flower parts are removed, and cuttings dipped in a solution of Kelpak and watered before propagation. The cuttings are placed in a medium suitable for fynbos (a mixture of fine-milled bark and perlite). The excess powder is allowed to stay on the cutting, and where it is placed in the moist medium, by first making a thin hole with a sterile wire and then placing the cutting in the hole. The tray with cuttings is labelled and then placed in the propagation mist house.

The mist house has a temperature of 25(±2)ºC, and it also sprays water every 15 minutes for 5 seconds to keep the rooting medium moist, leaves cool and moist, while the beds are heated and kept at a warm temperature of 22–25ºC. The cuttings root after 2–3 months, are hardened off for a week in a shady area and then potted into 2 kg nursery bags, using a fynbos soil mix. They are watered regularly and given organic fertilizers once a month for increased growth, and planted into the garden when ready.

Staavia radiata needs a sunny position with free air circulation, in sandy, acidic soil. It is ideal for fynbos gardens. Plants are long-lived and resprout after being cut back.
