Description

BRIEF DESCRIPTION OF THE PHOTOGRAPH

(1) The accompanying photograph illustrates the overall appearance of the new Iberis 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 Iberis plant.

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

DETAILED BOTANICAL DESCRIPTION

(3) The aforementioned photograph and following observations and measurements describe plants grown during the spring in 17-cm containers in an outdoor nursery in Aalsmeer, The Netherlands and under cultural practices typical of commercial Iberis production.
