Abstract

A new and distinct cultivar of pot chrysanthemum plant characterized by its single flower form and flowers which have several rows of pink ray florets which possess good substance and long life and which have a minimal production of pollen. This new variety is not temperature sensitive, has an upright pot habit and good breaking ability, and an abundant production of flowers when grown as a spray plant.

Description

BACKGROUND OF THE NEW PLANT

My new variety of chrysanthemum plant originated as a seedling of unidentified parentage and was discovered by me in 1972, at Westfield-Woking, Surrey, England, among a group of random pollinated plants cultivated by me in the course of a breeding program carried on by me with the object of developing new chrysanthemum varieties suitable for production for the commercial market. This new plant was asexually reproduced by me at Westfield-Woking, Surrey, England, in 1972, by cuttings from the original plant, and then tested for its retention of its originally noted distinctive characteristics. Since 1972, asexual propagation of this new variety has been carried on at West Chicago, Ill., and at Cortez, Fla., by means of vegetative cuttings, and many generations of the plant so propagated have demonstrated that its novel and distinctive characteristics hold true from generation to generation and appear to be firmly and permanently fixed.

DESCRIPTION OF THE DRAWING

This new variety of chrysanthemum plant is illustrated by the accompanying photographic drawing which shows a potted plant display of the flowers in full color as nearly true as is reasonably possible to obtain by conventional photographic procedures, and which shows, by pen-and-ink drawings, the distinctive configuration of the leaves of the new plant taken at several stages of maturity.

This new chrysanthemum plant is particularly distinguished by its single flower form and its pink ray florets, of which there are several rows, which possess good substance and long life with a minimal production of pollen. This variety is also characterized by its small foliage, strong stems, and good breaking ability, with 4 to 6 breaks when manually pinched, and by its abundant production of flowers when grown as a spray pot.

This variety is not temperature sensitive and can be flowered the year around on medium treatment, flowering nine weeks after commencement of short days and requiring but one 2500 ppm B-9 application during the optimum growing periods.
