Abstract
A new and distinct cultivar of Cercis plant named ‘JN21’, characterized by its compact and upright plant habit; relatively vigorous growth habit and rapid growth rate; relatively large, thick and glossy leaves that are dark red purple in color when developing; and good garden performance and cold hardiness.
Description
Botanical designation: Cercis canadensis.
Cultivar denomination: ‘JN21’.
The present invention relates to a new and distinct Cercis plant, botanically known as Cercis canadensis, commercially referred to as Eastern Redbud and hereinafter referred to by the name ‘JN21’.
The new Cercis plant is a product of a planned breeding program conducted by the Inventors in Belvidere, Tenn. The objective of the breeding program was to develop new Cercis plants with large attractive leaves and cold hardiness.
The new Cercis plant originated from an open-pollination of an unnamed selection of Cercis canadensis, not patented, as the female, or seed, parent with an unknown selection of Cercis canadensis as the male, or pollen, parent. The new Cercis plant was discovered and selected by the Inventors as a single plant within the progeny of the stated open-pollination in a controlled nursery environment in Belvidere, Tenn. in April, 2015.
Asexual reproduction of the new Cercis plant by chip budding onto a proprietary seedling Cercis rootstock in a controlled environment in Belvidere, Tenn. since September, 2015 has shown that the unique features of this new Cercis plant are stable and reproduced true to type in successive generations.
Plants of the new Cercis have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘JN21’. These characteristics in combination distinguish ‘JN21’ as a new and distinct Cercis plant:
-
- 1. Compact and upright plant habit.
- 2. Relatively vigorous growth habit and rapid growth rate.
- 3. Relatively large, thick and glossy leaves that are dark red purple in color when developing.
- 4. Good garden performance and cold hardiness.
Plants of the new Cercis can be compared to plants of the female parent selection. Plants of the new Cercis differ from plants of the female parent selection in the following characteristics:
-
- 1. Leaves of plants of the new Cercis are larger, thicker and glossier than leaves of plants of the female parent selection.
- 2. Developing leaves of plants of the new Cersis are dark red purple in color whereas developing leaves of plants of the female parent selection are green in color.
Plants of the new Cercis can be compared to plants of Cercis reniformis ‘Oklahoma’, not patented. In side-by-side comparisons, plants of the new Cercis differ primarily from plants of ‘Oklahoma’ in the following characteristics:
-
- 1. Plants of the new Cercis are more vigorous than plants of ‘Oklahoma’.
- 2. Plants of the new Cercis have larger leaves than plants of ‘Oklahoma’.
- 3. Plants of the new Cersis are more cold hardy than plants of ‘Oklahoma’.
The accompanying colored photographs illustrate the overall appearance of the new Cercis plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Cercis plant.
The photograph on the first sheet is a side perspective view of a typical three-year old tree of ‘JN21’ grown in an outdoor nursery.
The photograph on the second sheet is a close-up view of the upper surface of typical leaves of ‘JN21’.
The photograph on the third sheet is a close-up view of typical flowers of ‘JN21’.
The aforementioned photographs and following observations, measurements and values describe trees grown during the spring and summer in an outdoor nursery in Belvidere, Tenn. and Park Hill, Okla. and under cultural practices typical of commercial Cercis production. During the production of the plants, day temperatures averaged 30° C. and night temperatures averaged 26° C. Plants were two years old when the description was taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
