Chrysanthemum named California Golddust

Abstract

A new variety of Chrysanthemum morifolium of the spray type particularly distinguished by its pale yellow blossoms, the petals of which are whorled on the receptacle in a double formation having a very close imbricated arrangement providing a rather solid appearing flower. The plant has a profuse recurrent production of flowers borne singly on stems forming part of the spray formation, the blooming habit being under controlled photoperiod growing conditions. The flowers are borne on individual stems of about eight inches in average length comprising parts of spray formations carried on tall main stems, the plant itself having a prolific branching character, if pinched, with a vigorous, upright growth habit and a total height of three to four feet.

Description

BACKGROUND OF THE INVENTION

This new Chrysanthemum variety was discovered by me on Oct. 1, 1987, as a sport of the variety `Moneymaker` (patent applied for) being grown in my nursery at Carpinteria, Calif. The new flower with its bright light yellow coloration and the relatively dense imbrication of its relatively broad petals was noticed immediately as I inspected the field of `Moneymaker` being grown to provide stem cuttings for commercial propagation at the nursery of Westland Floral in Carpinteria. Continued propagation of my new discovery provided a fair showing that the novel characteristics of this new variety would hold true from generation to generation and appeared to be firmly fixed. Propagation of this new plant is being carried on at the Westland Floral Nursery by means of stem cuttings.

DESCRIPTION OF THE DRAWINGS

My new Chrysanthemum variety is illustrated by the accompanying drawings, which in the upper view shows a group of flowering stems of the new plant to illustrate the general character and its profuse production of blooms; and in the lower view shows a group of the flowers, one of which has been hand painted to show the true color of the novel blossom.

DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of my new Chrysanthemum variety based upon observation made in the early Fall of 1987 at Carpinteria, Calif., the color designations being according to The R.H.S. Colour Chart published by The Royal Horticultural Society of London, England.

This new variety of Chrysanthemum most nearly resembles `Moneymaker` in its general physiology but differs materially in the color of its ray florets and the appearance of the disc. The difference between the sport and its parent is shown by the following flower comparison table which is based upon direct comparisons made at Westland Floral Nursery at Carpinteria, Calif.
