Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0016] The accompanying photographs illustrate 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.

[0017] The photograph on the first sheet (FIG. 1 of 2) comprises a side perspective view of a typical flowering stem of DLFHED3 grown as a spray-type cut flower.

[0018] The photograph on the second sheet (FIG. 2 of 2) is a close-up view of lower (top of the photographic sheet) and upper (bottom of the photographic sheet) surfaces of typical inflorescences (left) and leaves (right).

DETAILED BOTANICAL DESCRIPTION

[0019] The aforementioned photographs and following observations and measurements describe plants grown during the spring in ground beds in a glass-covered greenhouse in Maasdijk, The Netherlands and under cultural practices typical of commercial cut Chrysanthemum production. Plants were initially given long day/short night treatments followed by short day/long night treatments to induce flower initiation and development. During the production of the plants, day temperatures ranged from 18 C. to 22 C., night temperatures ranged from 20 C. to 25 C. and light levels averaged 8 klux. Plants were grown as single-stem spray-type plants and were ten weeks old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used. [0020] Botanical classification: Chrysanthemum X morifolium DLFHED3. [0021] Parentage: [0022] Female, or seed, parent.Proprietary selection of Chrysanthemum x morifolium identified as code number DB 31733, not patented. [0023] Male, or pollen, parent.Proprietary selection of Chrysanthemum x morifolium identified as code number DB 38838, not patented. [0024] Propagation: [0025] Type.Terminal vegetative cuttings. [0026] Time to initiate roots, summer.About six days at temperatures about 24 C. [0027] Time to initiate roots, winter.About eight days at temperatures about 22 C. [0028] Time to produce a rooted young plant, summer.About twelve days at temperatures about 24 C. [0029] Time to produce a rooted young plant, winter.About two weeks at temperatures about 22 C. [0030] Root description.Fine, fibrous; typically creamy white in color, actual color of the roots is dependent on substrate composition, water quality, fertilizers, substrate temperature and physiological age of roots. [0031] Rooting habit.Freely branching, medium density. [0032] Plant description: [0033] Plant and growth habit.Herbaceous decorative-type cut flower that is typically grown as a single stem spray-type; upright plant habit; vigorous growth habit and moderate to rapid growth rate. [0034] Pathogen & pest resistance: Plants of the new Chrysanthemum have been observed to be relatively resistant to Fusarium oxysporum f.sp. chrysanthemi. To date, plants of the new Chrysanthemum have not been observed to be resistant to pests and other pathogens common to plants grown under commercial conditions. [0035] Temperature tolerance: Plants of the new Chrysanthemum have been observed to tolerate temperatures ranging from about 12 C. to 35 C. and to be suitable for USDA Hardiness Zones 8 to 10.
