Abstract

A new and distinct cultivar of Cercis tree named ‘JN7’, characterized by its upright vase-shaped plant habit with relatively narrow branching angle; vigorous growth habit; and good garden performance.

Description

Botanical designation: Cercis canadensis.
Cultivar denomination: ‘JN7’.
BACKGROUND OF THE INVENTION
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 ‘JN7’.
The new Cercis plant originated from an open-pollination in Belvidere, Tenn. of an unidentified proprietary 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 the fall of 2007.
Asexual reproduction of the new Cercis plant by bud grafting onto a proprietary seedling Cercis rootstock in a controlled environment in Belvidere, Tenn. since 2008 has shown that the unique features of this new Cercis plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Cercis have not been observed under all possible 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 ‘JN7’. These characteristics in combination distinguish ‘JN7’ as a new and distinct Cercis plant:
    • 1. Upright vase-shaped plant habit with relatively narrow branching angle.
    • 2. Vigorous growth habit.
    • 3. Good garden performance.
Plants of the new Cercis can be compared to plants of the female parent selection. Plants of the new Cercis differ primarily from plants of the female parent selection in plant habit as plants of the female parent selection are flat-topped to rounded in overall shape. In addition, plants of the new Cercis are more uniform than plants of the female parent selection.
Plants of the new Cercis can also be compared to plants of Cercis canadensis ‘Greswan’, disclosed in U.S. Plant Pat. No. 19,654. In side-by-side comparisons, plants of the new Cercis differed primarily from plants of ‘Greswan’ in the following characteristics:
    • 1. Plants of the new Cercis had an upright vase-shaped plant habit whereas plants of ‘Greswan’ were upright and outwardly arching.
    • 2. Branch angle for plant of the new Cercis was about 45° from vertical whereas branch angle for plants of ‘Greswan’ was about 60° from vertical.
    • 3. Plants of the new Cercis were more vigorous and grew faster than plants of ‘Greswan’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
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 tree of ‘JN7’.
The photograph on the second sheet is a side perspective view of a typical flowering tree of ‘JN7’.
The photograph on the third sheet is a close-up view of a typical tree of ‘JN7’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe trees grown during the spring in seven-gallon containers in an outdoor nursery in Park Hill, Okla. and under cultural practices typical of commercial Cercis production. During the production of the plants, day temperatures averaged 22° C. and night temperatures averaged 9° C. Plants used for the photographs were six years old and plants used for the description were three years old. 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.
