Sucker (botany)

Basal shoots, root sprouts, adventitious shoots, water sprouts and suckers are various types of shoots which grow from a bud at the base of a tree or shrub or from adventitious buds in its roots. A plant that produces suckers (root sprouts) is referred to as surculose. Root suckers may emerge some distance from the originating plant, are considered a form of vegetative dispersal, and may originate a habitat patch where that tree is the dominant species. Suckers also may arise from the roots of trees that have been cut down.

In botany, a 'sucker' is a plant growing not from a seed but from a meristem of the root at the base or at a certain distance from a tree or shrub.

This is a phenomenon of natural asexual spread, also known in plants as vegetative reproduction. It is a plant propagation strategy and the complex of individuals formed by a mother plant and all its clones produced form a single genetic individual, a genet. The plant suckers are clones from the mother plant. The plant will have a genome identical to that from which it arose. Many species of plant reproduce through vegetative reproduction, such as the Canada thistle, cherry, Apple, Ligustrum, hazel, Tree of Heaven, Asimina triloba. The guava, a tropical tree, is also known to propagate through basal shoots.
