Propagation of Blepharis capensis (L.f.) Pers. var. prostrata Oberm.
Blepharis capensis (L.f.) Pers. var. prostrata Oberm. is commonly propagated by seeds and stem cuttings.
Propagation by Seeds
The seeds of Blepharis capensis (L.f.) Pers. var. prostrata Oberm. can be collected when they are mature and ripe, usually in late summer or early fall. The collected seeds can be sown in a well-draining, sandy soil mixture in flats or pots. The flats should be kept moist and in a warm, sunny location. Germination usually occurs in two to three weeks.
Propagation by Stem Cuttings
Stem cuttings can also be taken to propagate Blepharis capensis (L.f.) Pers. var. prostrata Oberm. The cuttings should be taken from healthy plants that are actively growing. The cuttings should be four to six inches long and should be taken from the tips of the stems. The lower leaves should be removed and the cuttings should be dipped in a rooting hormone. The cuttings can be planted in a well-draining soil mixture and should be kept moist and in a warm, bright location. Roots should start to form in two to three weeks.
It is important to take care not to overwater the cuttings or allow them to dry out, as this can cause them to die before they have a chance to root.
