CONT: Plants with limbs that grow down, instead of up, can be spectacular. Horticulturally, the reason for this growth habit is a genetic mutation. Most plants have a central growth point that remains dominant, and the trunk and limbs grow vertically. In the weeping tree category, this growth control is interrupted. The new layer of growth is somehow superimposed over the previous layer, and is more horizontal than vertical. This growth pattern is known as plagiotropism.
