CHRYSANTHEMUM PLANT Filed Aug. l0, 1972 4v'United States Patent O U.S. Cl. PIL-78 1 Claim ABSTRACT OF THE DISCLOSURE A new variety of chrysanthemum plant particularly suited for summertime greenhouse production as a pot plant and having a dependable nine-week response for photoperiod culture. This is a vigorous variety producing a strong, well branched plant when grown as a pot mum and appears to have no tendency to heat delay in warm seasons. In the wintertime, the owers of this variety develop a light bronze coloring as they open but as the seasons become warmer, the ower color is a good and attractive yellow.

BACKGROUND OF THE NEW PLANT This new chrysanthemum variety was developed as a seedling of unknown parentage resulting from random crossing of greenhouse plants during the course of an extensive breeding program carried on by me and under my direction with the object of producing new and distinctive chrysanthemum varieties having improved characteristics of growth, response, and flower form and color. This plant was discovered by me in November 1968 at West Chicago, Ill., and asexual propagation, at West Chicago, Ill. by means of cuttings from the original plant, having demonstrated this variety to have good characteristics for summertime flowering, resulted in this plant being selected for trials which proved the plant to have commercial value. Extensive propagation of this new variety by means of vegetative cuttings, at West Chicago, Ill., and at Cortez, Fla., has shown the distinctive features of the plant to hold true from generation to generation and to be rmly fixed.

DESCRIPTION OF THE DRAWING This new variety of chrysanthemum plant is illustrated by the accompanying drawings which show the color and form of the flower as nearly true as is reasonably possible by conventional photographic procedures, and which show the conguration of typical specimens of the leaves by pen-in-ink sketches.

This new variety of chrysanthemum plant most nearly resembles the variety Yellow Mandalay (unpatented). This variety is more vigorous than Yellow Mandalay and trials have shown it to be better suited for summertime flowering since it does not have any tendency to heat delay as does Yellow Mandalay.

The flowering vresponse of this new variety is nine weeksv consistently,v this -plant lflowering about vfour days earlier than Yellow Mandalay.` In wintertime, this variety develops a light bronze coloring as the flower opens. The ower color becomes;a good yellow, however, as' the seasons become warmer.

1. A new and distinct variety of chrysanthemumplant,

substantially as herein shown and described, characterized by its dependable nine-week response and vigorous growth,fitslack-of tendency to heat delay `during summertime flowering, and its capability of producing a strong well branched plant when grown as a pot plant.
