Description

BRIEF DESCRIPTION OF THE PHOTOGRAPH

(1) The accompanying colored photograph illustrates the overall appearance of the new Erysimum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. 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 Erysimum plant.

(2) The photograph is a top perspective view of a typical flowering plant of ‘Doerywaberlem’ grown in a container.

DETAILED BOTANICAL DESCRIPTION
