Proliferation is a form of natural vegetative reproduction whereby plantlets or offsets (foliar embryos) are produced on leaves or stems of the mother plant, also known as vivipary.

Haemanthus species can be multiplied by using leaves and bulblets that are formed on the leaves. Leaves must be kept in a cool dry place and bulblets are formed in about 4 to 8 weeks.

Leaves that form bulblets are usually sections that are very close to the main bulb that are cutaway (old leaves or new leaves).

Leaf proliferation can be used to increase bulbs that do flower but do not make many seeds. On leaf proliferations up to 10 bulblets can form. The leaf section with the bulblets can be planted and bulblets continue to grow until big enough to be planted in their individual pots.
