plant named ‘Balupteam’

Abstract

A new and distinct cultivar of Coreopsis plant named ‘Balupteam’, characterized by its single-type, creamy-white colored inflorescences, medium green-colored foliage, and moderately vigorous, compact-mounded growth habit, is disclosed.

Description

Latin name of genus and species of plant claimed: Coreopsis hybrid.

Variety denomination: ‘Balupteam’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Coreopsis plant botanically known as Coreopsis hybrid and hereinafter referred to by the cultivar name ‘Balupteam’.

The new cultivar originated in a controlled breeding program in Santa Paula, Calif. during June 2012. The objective of the breeding program was the development of Coreopsis cultivars having large inflorescences, substantially continuous blooming throughout the summer, and mounded growth habits.

The new Coreopsis cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is the proprietary Coreopsis hybrid breeding selection coded 79571-12, not patented, characterized by its single-type, light creamy-white colored inflorescences, medium green-colored foliage, and moderately vigorous, semi-upright growth habit. The male (pollen) parent of the new cultivar is the proprietary Coreopsis grandiflora breeding selection coded 87067-1, not patented, characterized by its semi-double-type, light yellow-colored inflorescences, medium green-colored foliage, and moderately vigorous, compact-mounded growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during June 2013 in a controlled environment in Santa Paula, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings since June 2013 in Santa Paula, 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.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balupteam’ as a new and distinct cultivar of Coreopsis plant:

• • 1. Single-type, creamy-white colored inflorescences;
  • 2. Medium green-colored foliage; and
  • 3. Moderately vigorous, compact-mounded growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in having a more compact growth habit. Plants of the new cultivar differ from plants of the male parent primarily in having a different flower form and flower color.

Of the many commercially available Coreopsis cultivars, the most similar in comparison to the new cultivar is the Coreopsis cultivar BIG BANG ‘Star Cluster’, U.S. Plant Pat. No. 23,035. However, in comparison, plants of the new cultivar differ from plants of ‘Star Cluster’ in at least the following characteristics:

• • 1. Plants of the new cultivar have a ray floret color, in particular the color at the base of the ray floret, different from plants of ‘Star Cluster’;
  • 2. Plants of the new cultivar have larger leaves than plants of ‘Star Cluster’; and
  • 3. Plants of the new cultivar have smaller diameter inflorescences than plants of ‘Star Cluster’.

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 differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balupteam’. The plants were approximately 17 weeks old and grown in 1.7 gallon containers. Plants were finished outdoors for 7 weeks in West Chicago, Ill. Plants were given two pinches prior to transplant.

FIG. 2 illustrates a close-up view of an inflorescence of ‘Balupteam’.

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 July 2016 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings from stock plants and grown under conditions comparable to those used in commercial practice. The plants were grown utilizing a soilless growth medium in 1.7 gallon containers for approximately 17 weeks. Plants were given two pinches prior to transplant. For approximately 8 weeks after transplant, greenhouse temperatures were maintained at approximately 60° F. (15.6° C.) during the day and approximately 55° F. (12.8° C.) during the night. For the final 7 weeks, plants were grown outside in West Chicago, Ill. No supplemental lighting was provided. Measurements and numerical values represent averages of typical plants.
