Description

BACKGROUND OF THE INVENTION

The present invention is directed to a new and distinct variety of Chrysanthemum plant botanically classified as Dendranthema grandiflora. The varietal denomination of the new chrysanthemum is `GEDI M1`.

The female parent of the new variety is the variety known as `Celino` and the male parent is the variety known as `Ozenda` (U.S. Plant Pat. No. 10,419). The new variety has been asexually reproduced by vegetative cuttings in Ventura County, Calif. and the distinguishing characteristics are retained through successive generations of a sexual reproduction.

SUMMARY OF THE INVENTION

`GEDI M1` is a Chrysanthemum plant variety with white decorative/button-type flowers.

COMPARISON WITH PARENTS

`GEDI M1` has a smaller flower diameter than either parent. The new variety also has a round capitulum while `Celino` has a flat capitulum. Flower color of `Ozenda` is light lavender.

BRIEF DESCRIPTION OF ILLUSTRATIONS

The accompanying photographs show typical specimens of the plant and flowers of the new variety with colors being as nearly true as possible with illustrations of this type.

FIG. 2 is a closer view, showing inflorescence and foliage characteristics of the new cultivar in greater detail.

DESCRIPTION OF THE PLANT

The following description of the new variety is of specimens grown in a greenhouse in Ventura County, Calif. in the month of April. `GEDI M1` has not been observed under all possible environmental conditions. The phenotype may vary with variations in the environment such as temperature, light intensity, day length and cultural conditions. The color designations herein are from The Royal Horticultural Society Colour Chart except where general terms are used.

To produce a commercial product the plants may be pinched once about ten days after planting. It has been observed that the shelf life of `GEDI M1` is about 29 days and a response time of about 7 weeks. No treatment with growth retardant was used with plants described. Useful growing conditions include night temperatures of about 18.degree.-20.degree. C., day temperatures of about 20.degree.-30.degree. C. and about 5,000 to 6,000 foot-candles of light. The new variety is naturally blooming in September in Ventura County, Calif.
