Abstract
A hybrid of Cornus kousa and Cornus florida providing a new large-bracted dogwood, which is a vigorous, highly floriferous, small, flowering tree, more nearly like C. florida, the plant being low and spreading rather than upright as C. kousa, yet more densely branched and foliaged close to the ground as compared with C. florida and having a flowering period intermediate that of the parental species.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and distinct dogwood tree cultivar, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of its vigor and highly floriferous small flowering form similar to its pollen parent C. florida as to its low and spreading shape, densely branched and foliaged arrangement, and intermediate the two parent species as respects the characteristics of the overwintering flower buds, and time of flowering, this hybrid being highly sterile, and resistant to disease and insects.
