CHRYSANTHEMUM PLANT ,Filed Aug. 16, 1972 United States Patent O 3,486 CHRYSANTHEMUM PLANT Robert E. Danielson, West Chicago, Ill., assignor to Pan- American Plant Company, Chicago, Ill. Filed Aug. 16, 1972, Ser. No. 281,170 Int. Cl. A01l1 5/00 U.S. Cl. Plt.-78 1 Claim ABSTRACT OF THE DISCLOSURE A new irradiation mutation of the variety May Shoesmith (unpatented) having a very large globular flower of the standard incurved type and a deep yellow color. This variety has an eleven-week response, can be flowered the year around with photoperiod control, and is best suited for wintertime greenhouse culture.

BACKGROUND OF THE NEW PLANT This new variety was discovered by me in June 1971 as a sport resulting from a radiation program carried on to develop new colors of the variety May Shoesmith (unpatented). This sport was aseXually propagated under my direction at West Chicago, Ill., and has been found to be very similar in response and growth characteristics to its parent variety. Subsequent propagation of this new variety, by vegetative cuttings, at West Chicago, Ill., and at Cortez, Fla, has shown the novel color of this variety to be firmly fixed and to hold true from generation to generation.

DESCRIPTION OF THE DRAWING My new variety of chrysanthemum plant is illustrated by the accompanying drawings in which the form and color of the blooms are shown by photographic rendition, the colors being as true as is reasonably possible by conventional photographic procedures, and in which the distinctive configuration of the leaves is shown by penand-ink drawing.

DESCRIPTION OF THE NEW PLANT The following is a detailed description of my new variety of chrysanthemum plant with color designations according to Robert F. Wilsons Horticultural Colour Chart issued by The British Colour Council in collaboration with The Royal Horticultural Society of London, England.

This variety with its eleven-week response is most suited for wintertime culture in greenhouse, however, it still can be raised and flowered the year around. It produces large, well formed flowers, flowering with a very even response and producing very few culls.

I claim:

1. A new and distinct variety of chrysanthemum plant, substantially as herein shown and described, characterized by its very large, bright yellow blooms, its excellent production of well formed flowers, flowering with a very even eleven-week response and producing very few culls.
