Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The photographs of the new plant demonstrate the unique traits and the overall appearance of Salvia Moulin Rouge. The colors are as accurate as reasonably possible with color reproductions. Variation in ambient light spectrum, source and direction may cause the appearance of minor variation in color. The plant used in the photographs was a three-year-old plant grown in an open, full-sun trial garden at a wholesale perennial nursery in Zeeland, Mich. with supplemental water and fertilizer when needed.

(2) FIG. 1 shows the plant habit in full flower in a landscape.

(3) FIG. 2 shows a close-up of the flower scape with the buds, flowers, stems and calyxes.

DETAILED BOTANICAL DESCRIPTION

(4) The following descriptions and color references except where common dictionary terms are used are based on the 2015 edition of The Royal Horticultural Society Colour Chart. Salvia Moulin Rouge has not been observed under all possible environments. The phenotype may vary slightly with different growing environments such as temperature, light, fertility, soil pH, moisture and plant maturity levels, but without any change in the genotype. The following observations and size descriptions are based on three-year-old plants growing in an outdoor full-sun trial garden and greenhouse-forced two-year-old plants at a wholesale perennial nursery in Zeeland, Mich. Plants were given supplemental water and fertilizer. Plant growth regulators were used in the greenhouse trials only.
