  • Patent number: PP4627
    Abstract: A new and distinct variety of Pink Flowering Dogwood, botanically known as Cornus florida is provided. The new variety exhibits a rapid upright growth habit and most nearly resembles the Sweetwater Red Flowering Dogwood (non-patented), but primarily is distinguished therefrom by the distinctive coloration of the foliage (as illustrated). The foliage initially is light purple and changes to dark purple as the leaves mature. Such foliage coloration substantially is retained throughout the growing season and into the fall even when grown in full sunlight.SUMMARY OF THE INVENTIONThe new and distinct variety of Pink Flowering Dogwood tree was discovered in 1966 while growing within a block of approximately 250,000 Cornus florida seedlings on the cultivated nursery property of the assignee located near McMinnville, Tenn. The seed which yielded the new variety was planted in 1965 and likely was obtained from either the Pink Flowering Dogwood variety or the Sweetwater Red Flowering Dogwood variety.
