Abstract

A hybrid of Cornus kousa Hance and Cornus florida L. providing a new large-bracted dogwood, which is an exceptionally vigorous, highly floriferous, small, flowering tree, more nearly like C. kousa, being upright in habit rather than low and spreading like C. florida, yet more fully branched and spreading as compared with C. kousa and having a period of floral display that is intermediate to C. florida and C. kousa, exhibiting highly textured, rounded and overlapping white floral bracts that are larger than those of either parent plant.

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 cultivar of dogwood tree, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of its exceptionally high vigor and highly floriferous small flowering form, similar to its seed parent as to its upright, vase-shaped habit when young, becoming more fully branched and spreading with age, intermediate the two parents as to characteristics of the overwintering flower buds and time of flowering, exhibiting floral bracts of a size exceeding that of either parent as well as that of most plants of either parental species, and exhibits resistance to dogwood borers and "dogwood decline".
