Bi-color Flowering Dogwood

Mike Dana, Extension Landscape Horticulture Specialist, Department of Horticulture & Landscape Architecture, Purdue University

The next time your neighbor asks where you got the bi-color flowering tree (in this case a flowering dogwood, Cornus florida) such as a dogwood or a crabapple, tell them you “planned it that way,” when really, it exhibits the fact that you are a forgetful pruner. This dogwood is white and pink because it is a grafted tree and a root sucker from the rootstock (the white flowers) was not pruned out in a timely manner and has been allowed to grow up with the part of the tree from the scion (the pink flowers) which was the tree that was, presumably, originally purchased.
