Abstract

This chrysanthemum cultivar originated as a sport of the variety "Hartmann's Dignity" (U.S. Plant Pat. No. 4,377) and is distinguished by the pleasing light yellow color of its large composite and incurved standard blooms. Otherwise this new plant is about the same in its growth and blooming habits as the parent variety.

Description

BACKGROUND OF THE NEW PLANT

My new variety of chrysanthemum was discovered by me at West Chicago, Ill., growing as a sport in a field of plants of the variety "Hartmann's Dignity" (U.S. Plant. Pat. No. 4,377) being grown in greenhouse for commercial purposes, as well as part of a continuous program carried on for the development of new and improved chrysanthemum varieties. The nature of this sport, as well as its distinctive color, led me to reproduce it as a new plant by means of cuttings from the original stem and subsequent propagation of the new plant by vegetative cuttings through several successive generations has shown its distinctive character to hold true and to appear to be firmly fixed. This has resulted in the new plant being selected for commercial exploitation and its propagation on a commercial scale is now being done at Parrish, Fla., as well as at West Chicago, Ill.

DESCRIPTION OF THE DRAWINGS

My new chrysanthemum cultivar is illustrated by the accompanying drawings, of which sheet one is a hand-colored photograph showing the form and color characteristics of the blossoms of the new plant, and sheet two is a mechanical reproduction of photocopies of typical leaves of the new plant taken at various stages of maturity.
