Description

BRIEF DESCRIPTION OF THE PHOTOGRAPH

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

(2) The photograph is a side perspective view of a typical flowering plant of Domchryblus grown in a 14-cm container.

DETAILED BOTANICAL DESCRIPTION

(3) The aforementioned photograph and following observations and measurements describe plants grown during the spring in 14-cm containers in a glass-covered greenhouse in Fareham, Hampshire, United Kingdom and under cultural practices typical of commercial garden Chrysanthemum production. During the production of the plants, day and night temperatures ranged from 17 C. to 21 C. and light levels averaged 6,000 lux. Plants were grown under long day/short night conditions for about two weeks and then grown under short day/long night conditions to induce inflorescence initiation and development. Plants were ten weeks old when the photograph and detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, except where general terms of ordinary dictionary significance are used.
