Propagation of Adenandra Rotundifolia
Adenandra rotundifolia Eckl. & Zeyh., commonly known as the Cape Snowbush, is a South African shrub that is grown for its ornamental value. The plant is easy to propagate and can be propagated by various methods which include:
Seeds
Propagation of Adenandra rotundifolia can be done by seeds. The ripe seeds are sown in spring after soaking them overnight in warm water. A sandy soil mix is used for sowing and the seeds are kept moist until germination. Germination can take up to six weeks. Once the seedlings have reached a height of 3-4 inches, they can be transplanted into individual pots and grown until they are strong enough to be planted in the ground.
Cuttings
The Cape Snowbush can easily be propagated from cuttings taken from softwood or semi-hardwood. Cuttings should be taken in spring or summer and should be 8-10 cm long. Rooting hormone can be applied to hasten root formation. The cuttings are then planted in a mixture of sand and peat moss. Bottom heat of 20-25°C is ideal for rooting. The cuttings should be kept moist and transplanted when they have developed enough roots to withstand transplanting.
Layering
Adenandra rotundifolia can also be propagated by layering. This method is suitable for established plants. A stem is selected and a small section of bark is removed from the middle of the stem. The wounded stem is then covered with soil and kept moist. Once roots have formed, the new plant can be separated from the mother plant and planted in a new location.
Overall, Adenandra rotundifolia is an easy plant to propagate. With proper care and attention, the propagules can develop into healthy plants that will add beauty to any garden or landscape.
