Abstract
A new and distinct cultivar of Iberis plant named ‘Summer Snowdrift’, characterized by its pure white-colored flowers, dark green-colored foliage, and moderately vigorous, mounded-spreading growth habit, is disclosed.
Description
Latin name of genus and species of plant claimed: Iberis hybrid.
Variety denomination: ‘Summer Snowdrift’.
The present invention relates to a new and distinct cultivar of Iberis plant botanically known as Iberis hybrid and hereinafter referred to by the cultivar name ‘Summer Snowdrift’.
The new cultivar originated in a controlled breeding program in Guadalupe, Calif. The objective of the breeding program was the development Iberis cultivars that have high heat tolerance and a long flowering season.
The new Iberis cultivar is a colchicine-induced sport of is the proprietary Iberis hybrid breeding selection coded 16336, not patented, characterized by its pure white-colored flowers, dark green-colored foliage, and moderately vigorous, mounded-spreading growth habit. The colchicine treatment occurred in March 2013. The new cultivar was discovered as a side shoot and selected during July 2014 in a controlled environment in Guadalupe, Calif.
Asexual reproduction of the new cultivar by terminal stem cuttings since July 2014 in Guadalupe, Calif. 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.
The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Summer Snowdrift’ as a new and distinct cultivar of Iberis plant:
-
- 1. Pure white-colored flowers;
- 2. Dark green-colored foliage; and
- 3. Moderately vigorous, mounded-spreading growth habit.
Plants of the new cultivar differ from plants of the parent primarily in having a larger flower diameter, slightly darker green-colored foliage, and in continuing to freely flower even under high heat conditions.
Of the many commercially available Iberis cultivars, the most similar in comparison to the new cultivar is ‘White Heat’, U.S. Plant Pat. No. 28,674. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘White Heat’ in at least the following characteristics:
-
- 1. Plants of the new cultivar have larger flowers than plants of ‘White Heat’;
- 2. Plants of the new cultivar have more flowers per terminal corymb than plants of ‘White Heat’; and
- 3. Plants of the new cultivar have a more branches than plants of ‘White Heat’.
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 differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Summer Snowdrift’. The plants were approximately four months old. The plants were grown in one-gallon containers for approximately 11 weeks in a greenhouse in Elburn, Ill. Plants were given two pinches, one at one week before transplant and one two weeks after transplant.
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 June 2018 under natural light conditions in West Chicago, Ill.
The following descriptions and measurements describe approximately four-month old plants produced from cuttings from stock plants and grown under conditions comparable to those used in commercial practice. The plants were grown in one-gallon containers for approximately 11 weeks in a greenhouse in Elburn, Ill. Plants were given two pinches, one at one week before transplant and one two weeks after transplant. Greenhouse temperatures were maintained at approximately 65° F. to 70° F. (18.3° C. to 21.1° C.) during the day and approximately 55° F. to 60° F. (12.8° C. to 15.6° C.) during the night. No supplemental lighting was provided. Measurements and numerical values represent averages of typical plants.
