Abstract

A new variety of Chrysanthemum producing red daisy-type flowers.

Description

BACKGROUND OF THE INVENTION

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

The new variety was discovered as a natural branch mutation of the variety `Tripoli` (U.S. Plant Pat. No. 10,207) in Staden, Belgium. The new variety has been asexually reproduced by vegetative cuttings in Ventura County, Calif. and the distinguishing characteristics are retained through successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

`GEDI RT` is pot type Chrysanthemum plant variety that produces red, daisy-type flowers.

COMPARISON WITH PARENT

The new variety differs from its parent in producing red ray florets whereas ray florets of the parent are lavender.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph shows a typical specimen of the new variety with colors being as nearly true as possible with illustrations of this type.

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 RT` 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, with center bud removed. It has been observed that the shelf life of `GEDI RT` is about 20 days with the response time of about 9 weeks. No growth regulator is used with the plants described. Desirable growing conditions include average night temperatures of about 62.degree.-65.degree. F. and day temperatures of about 70.degree.-75.degree. F.
