Epicormic shoot

An epicormic shoot is a shoot growing from an epicormic bud, which lies underneath the bark of a trunk, stem, or branch of a plant.

Epicormic buds lie dormant beneath the bark, their growth suppressed by hormones from active shoots higher up the plant. Under certain conditions, they grow into active shoots, such as when damage occurs to higher parts of the plant,^[1] or light levels are increased following removal of nearby plants.^[2] Epicormic buds and shoots occur in many woody species, but are absent from many others, such as most conifers.^[3]
