Chrysanthemum plant named `GEDI RA8`

Abstract

A new plant 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 morifolium. The varietal denomination of the new chrysanthemum is `GEDI RA8`.

The new variety was discovered as natural whole plant mutation in a controlled planting of the variety `Alcala` (U.S. Plant Pat. No. 10,211) 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 RA8` produces red, daisy-type non-brittle, herbaceous flowers on a mounding perennial plant suitable for garden decoration.

COMPARISON WITH PARENTS

`GEDI RA8` differs from its parent in having red ray florets whereas `Alcala` ray florets are purple.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph shows a typical specimen of the plant and flowers 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 July. `GEDI RA8` 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 longevity of individual blooms of `GEDI RA8` is about 17 days and the response time is about 6.5 weeks. No growth retardant is used on the plants described. Useful growing conditions include night temperatures of about 62.degree.-65.degree. F. and day temperatures of about 70.degree.-75.degree. F. The variety is naturally blooming mid to late September in California.
