Carnation named Londaxie

Abstract

A new and distinct variety of carnation of the tall, monoflore type characterized by the unique color of its medium sized blooms which are borne on long, stiff stems, the color being intermediate that of the similar flower of "Barlo II", U.S. Plant Pat. No. 3,406, and "Baruklo" (unpatented), furthermore this new variety has a more serrated petal and a stiffer stem than those of the named varieties; the new plant is also distinguished by its vigorous, upright and tall growth habit with moderately abundant foliage and profusely produced blossoms during each of its recurrent blooming seasons.

Description

BACKGROUND OF THE NEW PLANT

Our new carnation cultivar is the result of breeding efforts carried on by us since 1978 with the object of developing new and distinctive varieties of carnations having attractive color and good quality of flower form and plant growth habits. This new plant originated as a seedling produced at La Londe, France, by a cross of selected and individually identified plants growing among breeding stock maintained by us at La Londe, and this plant was selected by us for propagation and test because of its unique coloration and apparently advantageous growth habit. The discovery plant was propagated by us at La Londe, France, by means of cuttings, and the newly propagated plants appeared to possess all of the distinctive characteristics of the parent plant. Continued propagation under our direction, by means of cuttings, through several successive generations, has demonstrated that the novel and distinctive characteristics of this new plant hold true from generation to generation and appear to be firmly fixed.

DESCRIPTION OF THE DRAWING

Our new carnation cultivar is illustrated by the accompanying photographic drawing which shows, in full color, a typical arrangement of buds, partially opened flowers and full blooms, the color rendition being as nearly true, as herein specified, as it is reasonably possible to obtain by conventional photographic procedures.

DESCRIPTION OF THE NEW PLANT

The following is a detailed description of our new carnation variety based upon characteristics of greenhouse grown plants observed at La Londe, France, in the Spring of 1983, the color designations being according to The R.H.S. Colour Chart of The Royal Horticultural Society at London, England.
