Gardeners' Notes:

Neutral Rickwebb On Jan 9, 2014, Rickwebb from Downingtown, PA wrote:

A woman plant enthusiast recommended this hybrid of American Flowering Dogwood x Kousa Dogwood for a homeowner at a retirement community where I do a lot of work. I posted four photos in 2014. It is one cultivar of the Stellar Series bred by a Dr Orton at Rutger's University in New Jersey. These trees are intermediate between the two species. I bet the fruit is sterile. One big reason for their introduction was the fear of Discula fungus disease introduced from East Asia hurting many Flowering Dogwoods a lot in the 1990's, but many American plants are still surviving well now and resistant selections also exist.

Lower and more spreading than most flowering dogwoods. This one branches quite low to the ground. Unfortunately, it is susceptible to powdery mildew so plant it in a well aerated area. Bracts are brilliant white.
