Description

BRIEF DESCRIPTION OF THE DRAWING

(1) The accompanying photographs were taken in October and illustrate the characteristics of a 4 year-old plant as grown in a garden in Hummelo, Netherlands. The photograph depicts the plant habit and foliage coloration of ‘Purple Tears’ in bloom (plant towards back of photo). The colors in the photograph may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Panicum.
