The present invention is directed to a new and distinct variety of chrysanthemum botanically classified as Dendranthema grandiflora. The varietial denomination of the new chrysanthemum is `Dark Ozenda`.

The new variety was discovered as a whole plant natural mutation of the variety `Ozenda` (U.S. Plant Pat. No. 10,419) 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

`Dark Ozenda` is a chrysanthemum plant variety that produces red-purple decorative-type flowers.

COMPARISON WITH PARENT

The new variety differs from its parent in having red-purple flowers.

BRIEF DECRIPTION 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. `Dark Ozenda` 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 `Dark Ozenda` is about 26 days with the response time of about 7 weeks. No growth regulator is used with the plants described. Desirable growing conditions include average night temperatures of about 62°-64° F. and day temperatures of about 70°-75° F.
