Arnold dogwood is derived from natural crosses between silky dogwood (Cornus amomum) and gray dogwood (Cornus racemosa).[1][2] Intermediate shrubs were first noted in the Arnold Arboretum by Alfred Rehder, who described and named the hybrid. The name is an allusion to the place of its discovery.
Classification
editThe Arnold dogwood is usually included in the dogwood genus Cornus as Cornus × arnoldiana Rehd., although it is sometimes segregated in a separate genus as Swida × arnoldiana (Rehd.) Soják.
