Seed Propagation
The easiest method of propagating Berkheya grandiflora is through seeds. The plant produces seeds in abundance, and these can be collected when the seed capsules turn brown. The seeds should be sown in well-draining soil, and kept moist until they germinate. It is best to sow the seeds in the spring or early summer.

Cuttings
Propagation through cuttings is also possible for Berkheya grandiflora. The best time to take cuttings is in the late summer. Select healthy stems with no flowers, and cut them from the plant. Remove the lower leaves, leaving only a few at the top, to reduce moisture loss. Dip the cut ends in rooting hormone, and then plant them in moist, well-draining soil. Cover the cuttings with plastic or a cloche, to maintain humidity. In a few weeks, new growth will appear, indicating the cutting has rooted. The new plants can then be transplanted into their permanent location.
Division
Berkheya grandiflora can also be propagated through division. Dig up the entire plant, and gently separate the rootball into sections. Each section should have a few leaves and a portion of the root system. Replant the sections in their permanent location, and water them thoroughly. Division should be done in the early spring or early fall.
