Chrysanthemum plant named ‘Jeanny Orange’

Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Jeanny Orange’, characterized by its decorative pompon-type inflorescences with elongated oblong-shaped, light orange-colored ray florets; strong and upright flowering stems; freely flowering habit; early and uniform flowering response; and good postproduction longevity.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Jeanny Orange’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium and referred to by the name ‘Jeanny Orange’.

The new Chrysanthemum is a naturally-occurring whole plant mutation of a proprietary selection of Chrysanthemum×morifolium identified as code number 00.4758,04, not patented. The new Chrysanthemum was discovered and selected by the Inventor on Sep. 20, 2002 as a single flowering plant within a population of plants of the parent selection in a controlled environment in Hensbroek, The Netherlands.

Asexual reproduction of the new Chrysanthemum by terminal cuttings in Hensbroek, The Netherlands since 2002, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

BRIEF SUMMARY OF THE INVENTION

The cultivar Jeanny Orange has 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 ‘Jeanny Orange’. These characteristics in combination distinguish ‘Jeanny Orange’ as a new and distinct cultivar:

• • 1. Decorative pompon-type inflorescences with elongated oblong-shaped, light orange-colored ray florets; typically grown as a spray-type.
  • 2. Strong and upright flowering stems.
  • 3. Freely flowering habit.
  • 4. Early and uniform flowering response.
  • 5. Good postproduction longevity.

Plants of the new Chrysanthemum can be compared to plants of the parent selection. In side-by-side comparisons conducted in Hensbroek, The Netherlands, plants of the new Chrysanthemum differed primarily from plants of the parent selection in ray floret coloration as plants of the parent selection had pink-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Yoko Ono, disclosed in U.S. Plant Pat. No. 12,566. In side-by-side comparisons conducted in Hensbroek, The Netherlands, plants of the new Chrysanthemum differed primarily from plants of the cultivar Yoko Ono in the following characteristics:

• • 1. Plants of the new Chrysanthemum were more vigorous than plants of the cultivar Yoko Ono.
  • 2. Plants of the new Chrysanthemum had larger and stronger leaves than plants of the cultivar Yoko Ono.
  • 3. Plants of the new Chrysanthemum had larger inflorescences with more ray florets per inflorescence than plants of the cultivar Yoko Ono.
  • 4. Plants of the new Chrysanthemum and the parent selection differed in ray floret coloration as plants of the cultivar Yoko Ono was green.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, 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 actual colors of the new Chrysanthemum.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering stem of ‘Jeanny Orange’.

The photograph at the bottom of the sheet comprises a close-up view of upper and lower surfaces of typical inflorescences and typical leaves of ‘Jeanny Orange’.

DETAILED BOTANICAL DESCRIPTION

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. The aforementioned photographs and following observations and measurements describe plants grown during the summer and autumn in Hensbroek, The Netherlands, under commercial practice in a glass-covered greenhouse. Plants were initially given long day/short night treatments followed by short day/long night treatments to induce flower initiation and development. During the production of the plants, day temperatures ranged from 17.5 to 30° C., night temperatures ranged from 18.5 to 24° C. and light levels were about five kilolux. Plants were pinched once and were about ten weeks from planting when the photographs and the description were taken.
