Description

BRIEF DESCRIPTION OF THE PHOTOGRAPH

(1) The accompanying colored photograph illustrates the overall appearance of the new Phlox 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 Phlox plant. The photograph comprises a side perspective view of typical flowering plant of ‘Dophlowowhi’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

(2) The aforementioned photograph and following observations, measurements and values describe plants grown during the end of winter and early spring in 17-cm containers initially in a glass-covered greenhouse and finished in an outdoor nursery in Aalsmeer, The Netherlands and under cultural practices typical of commercial Phlox production. During the production of the plants, day temperatures averaged 21° C. and night temperatures averaged 15° C. Plants were pinched one time two weeks after planting rooted young plants and plants were 37 weeks old when the photograph and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Second Edition, except where general terms of ordinary dictionary significance are used.
