Chrysanthemum plant named ‘Dark Bronze Cherie’

Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Dark Bronze Cherie’, characterized by its compact, upright, spreading and uniformly mounded plant habit; freely branching and moderately vigorous growth habit; small dark green-colored foliage; uniform and early flowering habit; freely flowering habit; small daisy-type inflorescences with dark bronze-colored ray florets; and good postproduction longevity.

Description

Botanical description: Chrysanthemum×morifolium.

Cultivar denomination: ‘Dark Bronze Cherie’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially grown as a potted Chrysanthemum and hereinafter referred to by the name ‘Dark Bronze Cherie’.

The new Chrysanthemum is a naturally-occurring whole plant mutation of the Chrysanthemum×morifolium cultivar Apricot Cherie, disclosed in U.S. Plant Pat. No. 12,961. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within a population of plants of the cultivar Apricot Cherie in February, 2003 in Brantford, Ontario, Canada. The selection of this plant was based on its unique ray floret coloration.

Asexual reproduction of the new Chrysanthemum by vegetative tip cuttings was first conducted in Brantford, Ontario, Canada in May, 2003. Asexual reproduction by cuttings has shown that the unique features of the new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Dark Bronze Cherie have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength 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 ‘Dark Bronze Cherie’. These characteristics in combination distinguish ‘Dark Bronze Cherie’ as a new and distinct potted Chrysanthemum cultivar:

• • 1. Compact, upright, spreading and uniformly mounded plant habit.
  • 2. Freely branching and moderately vigorous growth habit.
  • 3. Small dark green-colored foliage.
  • 4. Uniform flowering response.
  • 5. Typically grown as a center-budded or as natural spray type.
  • 6. Early flowering habit, eight-week response time.
  • 7. Freely flowering habit.
  • 8. Small daisy-type inflorescences with dark bronze-colored ray florets.
  • 9. Good postproduction longevity with plants maintaining good substance and color for about three weeks in an interior environment.

Plants of the new Chrysanthemum differ from plants of the parent, the cultivar Apricot Cherie primarily in ray floret color as plants of the cultivar Apricot Cherie have apricot pink-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Bronze Cherie, disclosed in U.S. Plant Pat. No. 9,702. In side-by-side comparisons conducted in Fort Myers, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Bronze Cherie primarily in ray floret color as plants of the new Chrysanthemum had darker bronze-colored ray florets than plants of the cultivar Bronze Cherie.

These photographs show 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 Chrysanthemum.

The photograph on the first sheet comprises a side perspective view of a typical flowering plants of ‘Dark Bronze Cherie’.

The photograph on the second sheet is a close-up view of typical inflorescences of ‘Dark Bronze Cherie’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring in Leamington, Ontario, Canada during the spring in a polycarbonate-covered greenhouse and under conditions and practices which approximate those generally used in commercial potted Chrysanthemum production. During the production of the plants, day temperatures averaged 22.5° C., night temperatures averaged 18° C. and light levels ranged from 4,000 to 6,000 foot candles. Four unrooted cuttings were directly stuck in 15-containers, exposed to long day/short night conditions, and pinched about two weeks later. At that time, the photoinductive short day/long night treatments were started. Plants used in the photographs and for the description were grown as natural spray types and were about two months old. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
