Abstract: A new plant variety of chrysanthemum producing white daisy-type flowers.
Claim: What is claimed is:

1. A new and distinct chrysanthemum plant of the variety

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 WT8`.

The new variety is a natural whole plant mutation discovered in a controlled planting 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 VenturaCounty, Calif. and the distinguishing characteristics are retained through successive generations of asexual reproduction.


`GEDI WT8` is a chrysanthemum plant that produces white daisy-type flowers.


`GEDI WT8` differs from its parent in having white ray florets whereas its parent has purple florets.


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.


The following description of the new variety is of specimens grown in a greenhouse in Ventura County, Calif. in the month of July. `GEDI WT8` has not been observed under all possible environmental conditions. The phenotype may vary withvariations 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 WT8` is about 19 days and the response time is about 7 weeks. No growth retardenthas been applied in the specimens described. Useful growing conditions include night temperatures of about F. and day temperatures of about F. The new variety is naturally blooming during late September tomid October in Ventura County, Calif.
