Chrysanthemum plant named Loyalty

Abstract

A new and distinct variety of chrysanthemum plant for greenhouse culture, characterized by the decorative form of its medium to large flowers with ray florets of deep pink which surround a central mass of closely grouped purple florets; by its year around 9-week response as a pot plant, its good breaking ability, its very dense, dark green foliage, and its tolerance to high soluble salt conditions.

Description

BACKGROUND OF THE NEW PLANT

This new chrysanthemum plant variety originated as a seedling of unidentified parentage which was discovered by me in 1972 among a group of plants grown by me at Westfield-Woking, Surrey, England, for breeding purposes. The unusual and lovely coloration of the blossoms of this plant and the dense growth of its foliage caused me to propagate the plant by cuttings for observation and test. Propagation of this new plant through successive generations, in my greenhouses at Westfield-Woking, Surrey, England, by vegetative cuttings has shown this plant to not only have considerable merit for commercial exploitation but also that its distinctive characteristics hold true from generation to generation and appear to be firmly fixed. This plant is now being asexually propagated and grown at West Chicago, Ill., and at Cortez, Fla., with full retention of all of its original distinctive characteristics.

DESCRIPTION OF THE DRAWING

My new chrysanthemum plant is illustrated by the accompanying full color photographic drawing, which shows the form and color characteristics of the flowers, and by a machine copied drawing showing photoprints of typical leaves of the new plant taken from representative positions along the plant stems. The photographic drawing shows the flower colors of the new plant as faithfully as it is reasonably possible to obtain by conventional professional photographic procedures.
