<i>Echinacea </i>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

BRIEF DESCRIPTION OF THE DRAWINGS

(1) 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.

(2) FIG. 1 shows the habit of the new plant in the flower.

(3) 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

(4) 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.
