<i>Monarda </i>plant named ‘Lavender Taffeta’

Abstract

The new and distinct cultivar of ornamental cultivar of Bee Balm Monarda plant named ‘Lavender Taffeta’ has medium-height, winter hardy, dense, vigorous clumping habit, dark green glossy foliage that exhibits strong resistance to powdery mildew, and numerous large flower heads of dark lavender-purple-colored flowers creating excellent flower coverage. The lower petals have darker strong purplish-red spots, and each flower head is subtended by burgundy-colored bracts. The new plant is attractive and useful in the garden landscape as a specimen, en masse, or as a container plant.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The photographs of the new plant demonstrate the unique traits of ‘Lavender Taffeta’ and the overall appearance of two-year-old plants in the full-sun, outdoor, research facility of a wholesale perennial nursery in Zeeland, Mich. The colors are as accurate as reasonably possible with color reproductions. Variations in the ambient light spectrum, source, intensity, and direction may cause the appearance of minor variations in color.

(2) FIG. 1 shows the new plant in flower in the research facility.
