Cornus × arnoldiana |
Cornus × arnoldiana, the Arnold dogwood, is a hybrid dogwood native to eastern North America. It is reported from Ontario, Missouri, Ohio, Pennsylvania, and Massachusetts.[1] It is a member of the dogwood genus Cornus and the family Cornaceae.
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
[edit]The 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.
