plant named ‘Rainbow Sherbet’

Abstract

The new and distinct cultivar of Echinacea plant named ‘Rainbow Sherbet’ of heavily branched plants, strong-stemmed, producing fragrant inflorescences with wide ray florets initially of orange-sherbet coloring transitioning to raspberry sherbet coloring and drooping and maturing to a light pinkish color. The center disk florets of raspberry-pink produce a large center pompon. The new plant has dark-green ovate foliage, produces flowers from mid-summer to late summer, and is suitable as a potted plant, for the landscape, and for cut flower arrangements.

Description

Botanical denomination: Echinacea hybrid.

Cultivar designation: ‘Rainbow Sherbet’.

STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(b)(6)

The first non-enabling disclosures of the claimed plant, in the form of a photograph and brief description on a website operated by Walters Gardens, Inc. on Feb. 1, 2022, followed by a photograph and brief description in the “Walters Gardens 2022-2023 Catalog” on Jun. 8, 2022. The claimed plant was first sold on May 4, 2022, to Quality Greenhouses and Perennial Farm, Inc. by Walters Gardens, Inc., who obtained the new plant and all information relating thereto from the inventor. No plants of Echinacea ‘Rainbow Sherbet’ have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior to the filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor and therefore a 35 U.S.C. §102(b) exception.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct cultivar of Coneflower from the genus Echinacea and given the cultivar name ‘Rainbow Sherbet’. The new plant was the result of a cross by the inventor of an unnamed proprietary hybrid known as 17-6-2 (not patented) as the female parent and an unnamed proprietary hybrid known as 17-2-3 (not patented) as the male in the summer of 2018, at a wholesale perennial nursery in Zeeland, Mich. The single seedling selected was evaluated initially in trials in the summer of 2019 at the same nursery and assigned the breeder code of 18-35-1.

Echinacea ‘Rainbow Sherbet’ has been asexually propagated at the same nursery by crown division and also using careful shoot tip tissue culture procedures and found to reproduce plants that exhibit all the characteristics identical to the original plant in successive generations.

Echinacea ‘Rainbow Sherbet’ is distinct from all other Coneflowers known to the inventor. The nearest comparison cultivars are: ‘Butterfly Kisses’ U.S. Plant Pat. No 24,458, ‘Strawberry Mousse’ (not patented), ‘Razzmatazz’ U.S. Plant Pat. No 13,894, ‘Delicious Candy’ (not patented), and ‘Secret Affair’ U.S. Plant Pat. No. 24,354.

‘Butterfly Kisses’ has a shorter habit with smaller inflorescences having light-pink ray florets and deeper pink disk florets that stay close to the same colors through maturity. ‘Strawberry Mousse’ is taller in habit, with inflorescences having ray florets of a lighter purplish-pink color that droop more, and the disk pompon is smaller and a lighter purplish-pink. ‘Razzmatazz’ is much taller in habit, has smaller inflorescences with light pinkish-purple ray florets, and a slightly darker pompom of medium purplish-pink disk florets. ‘Delicious Candy’ has a much shorter habit, with smaller inflorescences, the ray florets are a bright fuchsia color, and the disk florets are a reddish-orange. ‘Secret Affair’ has a taller and less upright habit, inflorescences with a single row of more drooping ray florets with a deeper pink, and a large pompon disk with fewer florets of deeper pink.

The female parent plant, 17-6-2, has smaller inflorescences having ray florets that begin reddish-colored and become more magenta-colored, and large disk florets of a deeper magenta color producing a pompon effect. The, male parent plant, 17-2-3, has smaller inflorescences having ray florets or near white and large disk florets of a creamy-yellow producing a pompon effect.

SUMMARY OF THE INVENTION

Echinacea ‘Rainbow Sherbet’ has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in the environment including: growing temperature, available sunlight, nutrients, water, etc. without a change in the genotype of the plant. The new plant is distinct from its parents and all other Echinacea known to the applicant in the following combined traits:

• • 1. Fragrant inflorescences with orange sherbet-colored ray florets;
  • 2. Wide ray florets transition to raspberry-sherbet color and mature to a light pinkish color;
  • 3. Very large disk florets of raspberry-pink;
  • 4. Center pompon of disk florets that have notched apices;
  • 5. Vigorous, compact, growth habit with heavy branching, and strong stems;
  • 6. Dark-green ovate foliage.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of ‘Rainbow Sherbet’ demonstrate the overall appearance of the plant including the unique traits. The drawings of the new plant are of a two-year-old plant grown in a full-sun trial garden in Zeeland, Mich. The colors are as accurate as reasonably possible with color reproductions. Some slight variations of color may occur as a result of lighting quality, intensity, wavelength, direction, or reflection.

FIG. 1 shows the habit of the new plant in the flower.

FIG. 2 shows a close-up from above of some inflorescences with flat ray florets at various stages of color and large center pompon.

DETAILED DESCRIPTION OF THE PLANT

The following description of Echinacea ‘Rainbow Sherbet’ is based on observations of two-year-old specimens grown in a partially-shaded greenhouse and in a full-sun trial garden in Zeeland, Mich. The new plant has not been tested in all environments and some phenotypic differences may occur with different environments without, however, any change in genotype. The color descriptions are based on the 2015 edition of The Royal Horticultural Society Colour Chart except where common dictionary descriptions are used.
