Preformed Plantlets
A small number of houseplants produce preformed plantlets along aerial shoots. Examples include spider plant, wax plant (Hoya) and strawberry begonia (Saxifraga stolonifera). Propagation is simple involving the removal of these plantlets (with or without aerial rootlets) and then inserting the base of the plantlets in a high-quality potting soil and treating the plantlet as if it were a stem cutting.
