Abstract

A new and distinct variety of Cercis canadensis eastern redbud plant, herein referred to by its cultivar name, ‘NC2016-2’, is provided which forms emerging purple colored foliage that matures to gold colored foliage. The new variety provides vegetation that is moderately vigorous and the growth habit is semi-weeping. The new variety is well suited for providing attractive ornamentation in the landscape.

Description

Botanical/commercial classification:

Latin name—Cercis canadensis.

Common name—eastern redbud.

Varietal denomination: ‘NC2016-2’.

SUMMARY OF THE INVENTION

The new variety of Cercis canadensis eastern redbud plant was selected from a population of second generation decedents from a hybrid cross. The controlled hybrid cross occurred during March, 2010 at Raleigh, N.C., U.S.A., 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) was an unnamed seedling (not patented). The male parent (i.e., the pollen parent) was the ‘JN2’ variety (U.S. Plant Pat. No. 21,451).

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

unnamed seedling x ‘JN2’

The new cultivar was discovered and selected as a single flowering plant within the second generation progeny of the above-stated hybrid cross. Selective study resulted in the identification of a single plant of the new variety in 2017 at Jackson Springs, N.C.

It was found that the new variety of Cercis plant of the present invention possesses the following combination of characteristics:

    • (a) forms attractive, foliage which emerges purple colored and matures to gold colored;
    • (b) exhibits semi-weeping growth habit; and
    • (c) provides moderately vigorous vegetation.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.

The new variety of the present invention can readily be distinguished from its ancestors. More specifically, the unnamed seedling female parent (i.e., the seed parent) displays weeping growth habit with purple colored foliage and the ‘JN2’ variety (i.e., the pollen parent) displays a non-weeping growth habit with foliage that changes from golden orange to speckled lime as it matures, whereas the new variety displays emerging purple-colored foliage that matures to gold colored foliage and semi-weeping growth habit.

The new variety has been found to undergo asexual propagation at Belvidere, Tenn. by chip budding since 2016. Asexual propagation by chip budding in Belvidere, Tenn. has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

The new variety has been named ‘NC2016-2’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs shows as nearly true as it is reasonably possible to make the same, in color illustrations of this character, typical specimens of the new variety. The Cercis plants of the new variety were approximately two years of age and were observed at Jackson Spring, N.C., U.S.A. while growing outdoors.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors described herein is The Royal Horticultural Society (“R.H.S.” Colour Chart), London, England, 2015 edition. The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The color values of the flowers were determined in April 2019 and the color values of the foliage were determined in June 2019 under natural light conditions in Cochranville, Pa.
