Abstract

A distinctive Dogwood variety of the Cornus florida L. genus and species exhibits an upright growth pattern and is easily cultivated, with improved mildew resistance, more upright carriage, and increased size of inflorescence including involucre, as compared to either the `Cloud Nine` or `Cherokee Chief` varieties.

Description

BACKGROUND OF THE INVENTION
This invention relates to a new cultivar of dogwood tree of the genus Cornus, species florida L, identified as `White Love`.
From seeds planted in 1986 in Saitama-ken, Japan, characteristics of a plant produced by chance which reached two meters in height were continuously observed since October of 1988. The instant variety was discovered in October, 1990 from one such plant and was stably reproduced asexually in Urawa, Saitama Prefecture, Japan, in February of 1991 by grafting in a quantity of 200. The characteristics of these trees were closely examined from March 1994 through February 1998. The trees in question were considered for their upright growth pattern to increase cultivation density, as well as ease of cultivation and aesthetic value.
SUMMARY OF THE INVENTION
The instant tree grows upright to an extremely great height at a rate of approximately 0.9 m per year. The branches have a large diameter and are brown in color, with no pattern, producing green shoots. The leaves are oval with acute tips and round bases. In maturity, the leaves are green with a medium gloss, turning red-orange in autumn. The inflorescence is an upward facing capitulum. The inflorescence including involucre is extremely large with a one-fold blossom. There are four involucral bracts which are long and wide, the yellow-white in color. The bracts open flat and remain so through maturity. The fruits are oval and somewhat longer and narrower than those of `Cloud Nine`. The age of flowering, bloom, and time of flowering are all medium. Resistance to heat and cold is medium. Resistance to mildew is good.
Compared to the `Cloud Nine` variety (U.S. Plant Pat. No. 2,112), the tree is taller and more upright. Additionally, the size of the inflorescence including involucre is greater. Mildew resistance is also improved.
Compared to the `Cherokee Chief` variety (U.S. Plant Pat. No. 1,710), the instant tree is more upright. The angle of the branch-intermediate portion to the trunk is smaller. The color of the involucral bract is yellow-white (J.H.S. C.C. No. 2701) (R.H.S. 156D) and the size of the inflorescences including involucre is larger. Additionally, the involucres have less twist. Mildew resistance is excellent.
BRIEF DESCRIPTION OF THE DRAWINGS
The new variety of Cornus is illustrated in the accompanying color photographs.
The first drawing illustrates a close-up view of the flower.
The second drawing illustrates a wider view, encompassing a number of flowers.
The third drawing illustrates an entire tree in full bloom.
The fourth drawing illustrates an entire tree without foliage.
Color notations refer to the color charts of the Japan Horticultural Society (J.H.S. C.C.), Royal Horticultural Society (R.H.S.), and ISCC-NBS Centroid Color Charts (ISCC-NBS).
