Chrysanthemum named `Hello Dolly`

Abstract

A new variety of Chrysanthemum morifolium, Ramat, for greenhouse culture having a nine-week response for recurrent year-round profuse production of medium sized, long lasting flowers, this plant being a sturdy and rapid grower with abundant foliage and being particularly suited for greenhouse culture within normal Chrysanthemum growing procedures.

Description

BACKGROUND OF THE NEW PLANT

This new variety of Chrysanthemum was discovered by me as a sport of the unpatented variety `Dolly` being grown in my greenhouse at Carpinteria, Calif., and this particular bloom quickly attracted my attention because of its considerably darker coloration than the parent variety, as well as that of the variety `Diana` (U.S. Plant Pat. No. 5,496) which is also being grown in my greenhouse. Because of the unusual coloration of this sport, I propagated it by means of cuttings through several successive generations and found that the propagated plants retained all of the physiological characteristics of the parent `Dolly`, except for flower coloration, and that the color characteristics of the new plant hold true from generation to generation and appear to be firmly fixed. This new plant provides a valuable addition to the market for this type of Chrysanthemum as exemplified by the success of `Dolly` and `Diana`.

DESCRIPTION OF THE DRAWING

My new variety of Chrysanthemum plant is illustrated by the accompanying full color photographic drawings which, in in the upper view, shows a cluster of blooms of my new variety, and the lower view shows a comparison of the blooms of the new plant with the blooms of `Diana` and `Dolly`, the flowers of the new plant being at the left side of the picture and the blooms of `Diana` being in the center of the group, the color characteristics of the flowers being shown as nearly true as is reasonably possible to obtain by means of conventional photographic procedures.

This new Chrysanthemum variety most nearly resembles `Diana`, U.S. Plant Pat. No. 5,496, and `Dolly`, which is an unpatented commercial variety. The form of my new Chrysanthemum is similar to that of `Dolly` but has fewer petals and the color is much darker. The color of the new variety is darker than `Diana` and also has fewer petals and the petals of my new variety are flatter and less rolled than those of `Diana` giving it a smoother and less ragged appearance.

The following is a comparison chart illustrating the color distinctions of my new variety `Hello Dolly` with respect to the parent plant `Dolly` and the similar plant `Diana`, as observed in my greenhouse at Carpinteria, Calif.
