Description

BRIEF DESCRIPTION OF THE PHOTOGRAPH

(1) The photograph of the new plant demonstrates the unique traits and the overall appearance of Sedum ‘Bright Idea’. The colors are as accurate as reasonably possible with color reproductions of this type. Variations in ambient light spectrum, source and direction may cause the appearance of minor variation in color. The plants used in the photographs were two-year-old plants grown in an open, full-sun trial garden at a wholesale perennial nursery in Zeeland, Mich. with supplemental water and fertilizer when needed. No plant growth regulators have been used.

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

(3) FIG. 2 shows a close-up of the foliage growing in intense light.

(4) FIG. 3 show the plant in early bud stages with reddish stems.

The phenotype may vary with changes in environment, climate, and cultural conditions without change however in the genotype. The color reference is in accordance with the 2015 edition of The Royal Horticultural Society Colour Chart except where general color dictionary terms are used.
