Description

Botanical designation: Celosia argentea.

Cultivar denomination: ‘ZANCESHA’.

CROSS-REFERENCED TO CLOSELY-RELATED APPLICATIONS & CLAIM TO FOREIGN PRIORITY

An European Plant Breeder's Rights application was filed for the Celosia ‘Zancesha’ on Nov. 4, 2021, application number 2021/2773. Foreign priority is claimed to this previously filed application.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Celosia plant, botanically known as Celosia argentea and hereinafter referred to by the name ‘Zancesha’.

The new Celosia plant is a product of a planned breeding program conducted by the Inventor in Rijsenhout, The Netherlands. The objective of the breeding program is to create new compact and uniform Celosia plants with attractive and unique leaf and flower coloration.

The new Celosia plant originated from a cross-pollination made by the Inventor in Rijsenhout, The Netherlands in October, 2017 of a proprietary Celosia argentea selection identified as code number 15-0131, not patented, as the female, or seed, parent with a mixture of pollen from a number of proprietary Celosia argentea selections, as the male, or pollen, parent. The new Celosia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rijsenhout, The Netherlands in June, 2018.

Asexual reproduction of the new Celosia plant by cuttings in a controlled greenhouse environment in Rijsenhout, The Netherlands since August, 2018 has shown that the unique features of this new Celosia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Celosia have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental 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 ‘Zancesha’. These characteristics in combination distinguish ‘Zancesha’ as a new and Celosia plant:

• • 1. Upright plant habit.
  • 2. Vigorous growth habit and rapid growth rate.
  • 3. Freely branching habit.
  • 4. Dark purplish red-colored leaves.
  • 5. Freely flowering habit.
  • 6. Purplish red-colored flowers arranged on spicate-type inflorescences.
  • 7. Good container performance.

Plants of the new Celosia differ primarily from plants of the female parent selection in leaf color as plants of the new Celosia have dark purplish red-colored leaves whereas plants of the female parent selection have green-colored leaves with random purple-colored spots.

Plants of the new Celosia can be compared to plants of Celosia hybrida ‘Zancemepur’, disclosed in U.S. Plant Pat. No. 31,267. In side-by-side comparisons, plants of the new Celosia and ‘Zancemepur’ differ primarily in the following characteristics:

• • 1. Plants of the new Celosia have dark purplish red-colored leaves whereas plants of ‘Zancemepur’ have medium green-colored leaves with random dark purplish red-colored spots.
  • 2. Flowers of plants of the new Celosia are slightly darker purplish red than flowers of plants of ‘Zancemepur’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Celosia 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 Celosia plant.

The photograph on the first sheet (FIG. 1) comprises a side perspective view of a typical flowering plant of ‘Zancesha’ grown in a container.

The photograph on the second sheet (FIG. 2) is a close-up view of typical fully expanded (left) and developing (right) leaves of ‘Zancesha’.

The photograph on the third sheet (FIG. 3) is a close up view of a typical flowering stem of ‘Zancesha’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the early spring in 9-cm containers in a glass-covered greenhouse in Rijsenhout, The Netherlands and under cultural practices typical of commercial Celosia production. During the production of the plants, day and night temperatures ranged from 20° C. to 22° C. Plants were grown under photoinductive long nyctoperiods, pinched one time about 2.5 weeks after planting and were ten weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
