The name Rhododendron comes from the Greek words “rodon” which means “rose” and “dendron” which means “tree”, hence Rose Tree.

The Laurelwood Arboretum Board of Directors has named its newly completed propagation greenhouse the “Dorothy Knippenberg Propagation Greenhouse” in recognition of Dorothy’s lifetime dedication to the hybridization of rhododendrons, azaleas, and other plants.
