1. A new and distinct cultivar of Echinacea plant named Balsomsolst, substantially as herein illustrated and described.

Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical inflorescence and foliage characteristics of the new cultivar. Colors in the photographs may differ slightly from the color values cited in the detailed description, which accurately describes the colors of Balsomsolst. The plants were approximately five months old. The plants were grown as three plants per pot in one-gallon containers for approximately 13 weeks in a greenhouse in Elburn, Ill. followed by 3 weeks in an open-sided polyhouse in West Chicago, Ill.

(2) FIG. 1 illustrates a side view of the overall growth and flowering habit of Balsomsolst.

(3) FIG. 2 illustrates a close-up view of an individual inflorescence of Balsomsolst.

DETAILED BOTANICAL DESCRIPTION

(4) The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.
