A keiki is a small plant which grows from
one of the nodes along the stem instead of a branch. The reason for this
is the accumulation of growth hormones at that point, this can be either
natural (as in this case) or it can be induced
by the application of keiki paste which is concentrated form of the
correct growth hormones.
Plants grown using this method will be
duplicates (again actually the same plant) and you can leave them in place
until they have a good root system and maybe two or three leaves. At this
point they can be removed and potted on, flowering size plants can be
obtained within two years using this method.
