USPP36029P2 - Cercis plant named ‘NC2017-113’ - Google Patents

Abstract

A new and distinct variety of Cercis plant, referred to by its cultivar name, ‘NC2017-113’, is disclosed. The new variety is characterized by its white-colored flowers. The new variety is also characterized by its small, thick, glossy, and green-colored foliage. A moderately slow growing and compact growth habit is displayed.

Description

Latin name of genus and species of plant claimed: Cercis canadensis.

Variety denomination: ‘NC2017-113’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Cercis plant botanically known as Cercis canadensis and hereinafter referred to by the cultivar name ‘NC2017-113’.

The new cultivar originated in a controlled breeding program in Raleigh, North Carolina in March 2010.

The new Cercis cultivar is the result of a controlled cross wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) of the new cultivar was Cercis ‘Texas White’ (not patented) and is characterized its white flowers, upright and rounded growth habit, and green foliage color. The male parent (i.e., the pollen parent) of the new cultivar is Cercis ‘Ace of Hearts’, U.S. Plant Pat. No. 17,161, and is characterized by its violet-colored flowers and compact habit.

The parentage of the new variety can be summarized as follows:

‘Texas White’ x ‘Ace of Hearts’

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study in summer of 2017 in a controlled environment in Jackson Springs, North Carolina resulted in the identification of a single plant of the new variety, which was selected for its white-colored flowers, small, thick, and glossy, green-colored foliage, and compact growth habit.

The new variety has been found to undergo asexual propagation in Belvidere, Tennessee by chip budding. This asexual reproduction 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 ‘NC2017-113’ as a new and distinct cultivar of Cercis plant:

• • (a) White-colored flowers,
  • (b) Small, thick, glossy, and green-colored foliage; and
  • (c) Compact growth habit.

The new variety of the present invention can readily be distinguished from its ancestors. More specifically, plants of the new cultivar differ from plants of ‘Texas White’ (i.e., the seed parent) in having a profusion of flowers and reduced internode length. In addition, plants of ‘Ace of hearts’ (i.e., the pollen parent) display violet-colored flowers, whereas plants of the new variety display white-colored flowers.

Moreover, the new variety can be readily distinguished from other similar non-parental varieties. Of the many commercially available Cercis cultivars, the most similar in comparison to the new cultivar is ‘Royal White’(not patented). However, plants of the new cultivar differ from plants of ‘Royal White’ in at least the following characteristic:

• • 1. Plants of the new cultivar have a more compact growth habit than plants of ‘Royal White’.
  • 2. Plants of the new cultivar have thicker and glossier leaves than plants of ‘Royal White’.

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 growth habit, flowering 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 ‘NC2017-113’. The plants in the photographs were taken at the Sandhills Research Station in Jackson Springs, North Carolina.

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.
