Chrysanthemum named Westland

Abstract

A new variety of chrysanthemum intended for glass house culture for cut flower production distinguished by the pink coloration of the quill-shaped ray florets of its uniquely formed medium-sized blooms, its vigorous upright growth habit, and its year around 9-week photoperiodic flowering response.

Description

BACKGROUND OF THE NEW PLANT

My new chrysanthemum cultivar originated as a seedling which resulted from my crossing of Yellow Augusta with Dark Flamenco as the pollen parent (both unpatented) in 1973 at De Lier, Holland, in the course of my efforts to produce improved chrysanthemums for the commercial market. I propagated this new plant at De Lier, Holland, by means of cuttings from the original plant and through successive generations by vegetative cuttings and determined that its distinctive characteristics hold true from generation to generation and thus appear to be firmly fixed.

This new plant is now being propagated for commercial purposes, by means of vegetative cuttings, at West Chicago, Ill., and at Cortez, Fla., U.S.A.

DESCRIPTION OF THE DRAWINGS

My new chrysanthemum cultivar is illustrated by the accompanying drawings, of which the first sheet is a full color photographic rendition of the full bloom inflorescence appearing on a typical main stem, the color shown being as nearly true as is reasonably possible to obtain by conventional photographic procedures; and the second sheet is a mechanical reproduction of a photoprint of typical leaves of the new plant.

DESCRIPTION OF THE NEW PLANT

The following is a detailed description of my new variety of chrysanthemum based upon observations made at West Chicago, Ill., U.S.A., in the Spring of 1978, with color designations according to The R.H.S. Colour Chart published by The Royal Horticultural Society of London, England.

Borne.--Singly and comprising a head of many florets borne on a receptacle, the flower peduncle being one of many carried in racemose fashion on a strong, upright main stem.

The particular distinctions of this new cultivar of chrysanthemum reside particularly in the spidery shape of its blooms with quill-shaped ray florets having a distinctive pink color, the blooms averaging about 8.5 cm. in diameter and the plant having particular usefulness as a cut spray capable of uniform flowering response the year around.

Claims

1. A new and distinct variety of chrysanthemum plant, substantially as herein shown and described, characterized by its unique quill-shaped ray florets of a light pink color radiating from a reddish disc, and its uniform year-around flowering response under 9-week photoperiodic control.
