Keiki
In horticulture, a keiki ( ) is a plant produced asexually by an orchid plant, especially "Dendrobium", "Epidendrum" ("sensu lato"), and "Phalaenopsis" orchids. The baby plant is an exact clone of the mother plant, sometimes flowering while still attached to the mother. The word "keiki" is Hawaiian for "baby" or "child", literally "the little one". In addition to keikis which grow on flower spikes, "Phalaenopsis" may occasionally produce basal keikis at the base of the orchid. Removing keikis. If a new plant is desired, the keiki should be left on the mother plant until it develops a healthy root system at  least 3 inches long and has two or three leaves (for a "Phalaenopsis") or canes ("Dendrobium"). For a "Phalaenopsis" keiki, this may take 6–12 months from when the keiki first forms. At this point, it can be carefully removed with a sharp knife and planted in its own pot. Some species orchids like "Phalaenopsis pulchra" frequently produce keikis, which flower while still attached to the mother plant. If a new plant is not desired, the keiki can be removed at any time. Removing the entire inflorescence after flowering is complete can prevent the production of keikis and result in a  tidier appearance for the plant. Hormone paste. Keiki paste is a cytokinin hormone which induces growth in the node of a "Phalaenopsis" inflorescence. It should not be confused with paste or powder containing auxins, which are used to force the production of roots. Nodes on "Phalaenopsis" spikes will form either vegetative growth (keiki) or floral growth (a branch with flower buds). If the node tissue is already differentiated so that it will become a floral branch, there is no way to change the result. The trick is to get the paste onto the node before it is differentiated. However, there  is no way to predict if an undifferentiated node will become a keiki or a floral branch.
