Claims
What is claimed is:
1. A new and distinct cultivar of Caryopteris plant named `Gold
Crest`, substantially as herein illustrated and described.
Description
Latin name of genus and species of plant claimed: Caryopteris
hybrid.
Variety denomination: `Gold Crest`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Caryopteris plant botanically known as Caryopteris hybrid and
hereinafter referred to by the cultivar name `Gold Crest`.
The new cultivar originated in a controlled breeding program in
Cochranville, Pa. during November 2010. The objective of the
breeding program was the development of Caryopteris cultivars
having increased cold hardiness and attractive foliage coloration
that doesn't fade under high light intensity.
The new Caryopteris cultivar is the result of open-pollination. The
female (seed) parent of the new cultivar is the proprietary
Caryopteris hybrid breeding selection coded X1503-4, not patented,
characterized by its medium violet-blue colored flowers, medium
grey-green colored foliage, and moderately vigorous, upright growth
habit. The male (pollen) parent of the new cultivar is unknown. The
new cultivar was discovered and selected as a single flowering
plant within the progeny of the above stated open-pollination
during June 2011 in a controlled environment in Cochranville,
Pa.
Asexual reproduction of the new cultivar by terminal stem cuttings
since June 2011 in Cochranville, Pa. and Elburn, Ill. has
demonstrated that the new cultivar reproduces true to type with all
of the characteristics, as herein described, firmly fixed and
retained through successive generations of such asexual
propagation.
SUMMARY OF THE INVENTION
The following characteristics of the new cultivar have been
repeatedly observed and can be used to distinguish `Gold Crest` as
a new and distinct cultivar of Caryopteris plant: 1. Medium
violet-blue colored flowers; 2. Medium green-colored foliage that
transitions to golden-colored foliage in spring and summer; 3.
Moderately vigorous, and mounded growth habit.
Plants of the new cultivar differ from plants of the female parent
primarily in having a golden-colored foliage in the spring and
summer, more branches per plant, and increased cold tolerance.
Of the many commercially available Caryopteris cultivars, the most
similar in comparison to the new cultivar is `Worcester Gold`, not
patented. However, in side-by-side comparison, plants of the new
cultivar differ from plants of `Worcester Gold` in at least the
following characteristics: 1. Plants of the new cultivar have a
more mounded habit than plants of `Worcester Gold`; and 2. Plants
of the new cultivar have wider leaves than plants of `Worcester
Gold`.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs show, as nearly true as it is
reasonably possible to make the same in color illustrations of this
type, typical flower and foliage characteristics of the new
cultivar. Colors in the photographs may differ slightly from the
color values cited in the detailed description, which accurately
describes the colors of `Gold Crest`. The plants were approximately
six months old and grown in 2-gallon containers for approximately
four months in an outdoor nursery environment in West Chicago, Ill.
Plants were given one pinch at approximately two weeks before
transplant.
FIG. 1 illustrates a side view of the overall growth and flowering
habit of `Gold Crest`.
FIG. 2 illustrates a close-up view of an individual inflorescence
of `Gold Crest`.
DETAILED BOTANICAL DESCRIPTION
The new cultivar has not been observed under all possible
environmental conditions to date. Accordingly, it is possible that
the phenotype may vary somewhat with variations in the environment,
such as temperature, light intensity, and day length, without,
however, any variance in genotype.
The chart used in the identification of colors described herein is
The R.H.S. Colour Chart of The Royal Horticultural Society, London,
England, 2015 edition, except where general color terms of ordinary
significance are used. The color values were determined in August
2019 under natural light conditions in West Chicago, Ill.
The following descriptions and measurements describe approximately
six-month old plants produced from cuttings from stock plants and
grown in a glass-covered greenhouse under conditions comparable to
those used in commercial practice. After approximately 10 weeks
rooted plants were transplanted into 2-gallon containers utilizing
a soilless growth medium. Plants were then transferred to an
outdoor nursery environment in West Chicago, Ill. and grown for
approximately four months. Plants were given one pinch at
approximately two weeks before transplant. Greenhouse temperatures
were maintained at approximately 70.degree. F. to 75.degree. F.
(21.1.degree. C. to 23.9.degree. C.) during the day and
approximately 60.degree. F. to 65.degree. F. (15.6.degree. C. to
18.3.degree. C.) during the night. Supplemental lighting was used.

plants. Botanical classification: Caryopteris hybrid `Gold Crest`.
