plant named ‘Power Rosé’

Abstract

A new cultivar of daisy-type spray pot Chrysanthemum, ‘Power Rosé’, characterized by it's early, uniform and free flowering habit, its inflorescences with ray florets that are light burgundy in color with bright yellow disk florets that open from buds that are burgundy in color, its vigorous freely branched growth habit, its small leaved dark green foliage and its uniform, rounded and outward spreading plant habit.

Description

Botanical classification: Chrysanthemum×morifolium.

Variety denomination: ‘Power Rosé’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of chrysanthemum plant, botanically known as Chrysanthemum×morifolium ‘Power Rosé’ (syn. Dendranthemum×grandiflora) and hereinafter by its cultivar name, ‘Power Rosé’.

The new Chrysanthemum, ‘Power Rosé’, was discovered by the Inventors as a naturally occurring branch mutation of Chrysanthemum cultivar ‘Power Purple’ (U.S. Plant Pat. No. 19,797) in a container in a greenhouse in September 2009 in Niagara on the Lake, Ontario, Canada.

Asexual reproduction of the new cultivar was first accomplished by one of the Inventors via stem cuttings in November 2009 in Niagara on the Lake, Ontario, Canada. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar of Chrysanthemum. These attributes in combination distinguish by ‘Power Rosé’ as unique from all other cultivars of Chrysanthemum known to the Inventors.

• • 1. The inflorescences of ‘Power Rosé’ have ray florets that are light burgundy in color with bright yellow disk florets that open from buds that are burgundy in color.
  • 2. ‘Power Rosé’ is early flowering with daisy-type inflorescences about 3.8 cm in diameter when grown as a spray pot.
  • 3. ‘Power Rosé’ exhibits a freely branched, uniform, rounded and outward plant habit.
  • 4. ‘Power Rosé’ exhibits a uniform flowering response.
  • 5. ‘Power Rosé’ exhibits small leaved dark green foliage.
  • 6. ‘Power Rosé’ exhibits a vigorous growth habit.

In comparison to the parent plant, ‘Power Purple’, ‘Power Rosé’ has ray florets that are lighter and more red in color than the ray florets of ‘Power Purple’, which are deep purple in color. Based on its growth habit, flowering response and flower type, ‘Power Rosé’ can be most closely compared to ‘Soft Cherie’ (U.S. Plant Pat. No. 8,802), which differs from ‘Power Rosé’ in having light purple colored ray florets and ‘Power Yellow’ (U.S. Plant Pat. No. 18,175), which differs from ‘Power Rosé’ in having yellow ray florets.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new chrysanthemum, ‘Power Rosé’. The photographs were taken of plants grown in a 5-inch pan pot planted with 3 rooted cuttings and grown under greenhouse conditions for 10 weeks in Niagara on the Lake, Ontario, Canada.

FIG. 1 is a photograph that provides a side view of a typical plant of ‘Power Rosé’ in bloom when grown as a spray-type.

The photograph in FIG. 2 provides a close up view of the inflorescences of ‘Power Rosé’.

The photograph in FIG. 3 provides a comparison between ‘Power Rosé’ (left) and ‘Power Purple’ (right).

The Colors in the photograph may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Chrysanthemum.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of plants of the new cultivar as grown in a 5-inch pan pot planted with 3 single pinched rooted cuttings and grown under greenhouse conditions at an average temperature of 65° F. for 10 weeks in Niagara on the Lake, Ontario, Canada. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
