Chrysanthemum named Orange Westland

Abstract

A new and distinct chrysanthemum cultivar originated as a sport developed by radiation of the variety "Westland" and distinguished by the unique and distinct orange coloration of its blooms. This new plant substantially retains the vigorous growth habit and physical characteristics of its parent and differs mainly by its orange color. The title of this application is the European denomination for this variety. In the United States, this variety is marketed as "Westland Orange".

Description

BACKGROUND OF THE NEW PLANT

This new chrysanthemum variety was developed by me at De Lier, Holland, in 1976 by radiation of the variety "Westland" (U.S. Plant Pat. No. 4,589) and was selected by me for propagation because of the unique and distinctive color of its flowers. This plant was reproduced by me with cuttings of its parent and propagation through successive generations has demonstrated that the novel characteristics of this sport hold true from generation to generation and appear to be firmly fixed. Propagation on a commercial scale is now being done by means of cuttings at West Chicago, Ill.; Cortez, Fla.; and at De Lier, Holland.

DESCRIPTION OF THE DRAWINGS

My new chrysanthemum cultivar is illustrated by the accompanying drawings, of which sheet 1 is a full color photographic rendition of a group of flowers of this plant taken when in full bloom, and sheets 2 and 3 are reproductions of photoprints of the front and back sides, respectively, of typical leaves of this new variety.
