ABSTRACT:
Variety denomination:
Cornus angustata
‘Elsbry’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Chinese evergreen dogwood
Cornus angustata
, hereinafter referred to by the cultivar name ‘Elsbry’. Prior to the designation of
Cornus angustata
as a distinct species in 1994, by Dr. T. R. Dudley of the United States National Arboretum, Washington, D.C. (see Phytologia. Vol. 76, pg. 428, 1994),
Cornus angustata
was classified as a variety of the Chinese kousa Dogwood,
Cornus kousa
, variety
angustata
Chun 1934.
The new ‘Elsbry’ variety of Dogwood was obtained by the Inventor in 1993 as a two to three year old seedling from a cultivated area in a Greenwood, S.C. nursery. It is believed that the seedling originated from seed collected in China. The plant has been cultivated in the Greenwood, S.C. garden of the Inventor where it was recognized to be a new and distinct cultivar of
Cornus angustata
having the unique characteristics described herein below.
Asexual reproduction of the new Dogwood by grafting and budding on seedling
Cornus kousa
and
Cornus florida
understocks has been undertaken at locations in Winchester and Belvidere, Tenn., and by softwood cutting in Hodges, S.C., which has shown in all instances that the unique features of the new ‘Elsbry’ Dogwood are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new ‘Elsbry’ Dogwood have not been observed under all possible environmental conditions. Accordingly, the phenotype may vary somewhat depending on changes in environmental conditions such as temperature, daylight, light intensity, nutrition and water status, without however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Elsbry’. The following characteristics in combination distinguish ‘Elsbry’ as a new and distinct cultivar of
Cornus angustata:
1. Vigorous growth rate.
2. Flowers produced at a young age, specifically, on 2 year old grafted plants.
3. Prolific flowering on an annual basis, specifically, heavier than other selections of
Cornus angustata
known to the Inventor.
4. Blooms 2 to 3 weeks later and over a larger period than other
Cornus angustata
and
Cornus kousa
Dogwood selections known to the inventor. In Greenwood, S.C. flowering commences in early May lasting through mid to late June.
5. Fruits form in early to mid September, extending ornamental interest into the fall season.
6. The evergreen foliage displays resistance to powdery mildew, as well as leaf and stem anthracnose, two major disease problems affecting many Dogwoods.
7. Foliage retention and deep green foliage coloration are maintained during the fall and winter months better than other selections of
Cornus angustata
known and observed by the Inventor.
8. Exhibits good cold hardiness, having withstood temperatures as low as 0° F. in Winchester, Tenn. The typical and observed hardiness zone ranges from between 6b to 9 on the U.S. Department of Agriculture Plant Hardiness Zone Map (1990).
