Abstract

A new and unique chrysanthemum for Fall gardens (early response) or for year-around four inch pot production (four weeks response), distinguished by its many vibrant pink daisy-like flowers, having bright yellow centers, borne on strong, upright stems; the plant having a vigorous, upright growth and profuse blooming habit whereby the plant forms a mound of color when garden bloomed in the Fall.

Description

BACKGROUND OF THE NEW PLANT

My new chrysanthemum cultivar originated as a seedling of unknown parentage growing among breeding stock maintained at West Chicago, Ill., where I discovered this new plant. The vibrant pink coloration of the daisy-like flowers of this plant prompted me to select it for propagation and test, which was done under my direction at West Chicago, Ill. Asexual propagation of this new plant by means of cuttings through several successive generations has shown that its novel characteristics hold true from generation to generation and appear to be firmly fixed. Propagation by cuttings for the commercial market is now being done at West Chicago, Ill., and at Cortez, Fla.

DESCRIPTION OF THE DRAWINGS

My new chrysanthemum cultivar is illustrated by the accompanying drawings, of which sheet 1 is a full color photographic rendition showing a garden plant in full bloom; sheet 2 is a photographic close-up face view of flowers of the new plant which has been hand-painted to show the true colors of the blooms according to specifications; and sheets 3 and 4, respectively, are prints of machine copies of the front and back-sides of typical leaves of this new variety.
