Spider Chrysanthemum named Autumn Champagne

Abstract

A new variety of Chrysanthemum morifolium of the incurved, spider type distinguished by its very large blooms having abundant ray florets of a light salmon color and carried on very tall stems, which are disbudded to present a single bloom with abundant foliage, the plant having a nine-week response with a moderate growth rate.

Description

BACKGROUND OF THE NEW PLANT

This new variety of Chrysanthemum was discovered by me as a sport of the variety `CF 4730 Pink Spider` (unpatented) growing in my nursery at Vista, Calif., and was selected for propagation because of its rather unusual flower color of a light salmon rather than pink, and asexual propagation was carried on through several successive generations by means of cuttings at Vista, and also at Carpinteria, Calif., whereby this new cultivar has been found to retain its distinctive characteristics from generation to generation, which appear to be firmly fixed.

DESCRIPTION OF THE DRAWINGS

My new variety of chrysanthemum plant is illustrated by the accompanying drawings, which show the form and color characteristics of the flower and foliage as nearly true as is reasonably possible to obtain by means of conventional photographic procedures, sheet one of the drawings showing a plurality of individual stems with flowers in successive stages of development from a newly opening bud to a fully developed bloom; and sheet two of the drawings shows a side-by-side comparison of the new flower with the bloom of the parent variety, the new variety being at the right of the parent.

THE REPRODUCTIVE ORGANS

My new cultivar is similar in many respects to the unpatented cultivar `CF 4730 Pink Spider` with respect to flower form and size; foliage size and shape and color; and plant height or growth.

My new cultivar is distinguished from `CF 4730 Pink Spider`, however, when grown under comparable conditions, by the fact that the flower color is of a bronzed appearance rather than a pink and the flower is more resistant to Botrytis.

Claims

1. The new and distinct spider type Chrysanthemum substantially as herein shown and described, particularly distinguished by the abundance of the incurved ray florets, the very large size of its blooms, and its resistance to Botrytis.
