Carnation variety `Londragel`

Abstract

A new spray carnation cultivar particularly distinguished by its relatively small flowers of substantially white coloration, with a cast of very light yellow from the central portion of the bloom, borne singly on straight, strong stems of medium length and having rather abundant foliage, the flowers blooming recurrently and profusely during the growing season and the plant having a vigorous, upright growth habit reaching a height of about 104 cm. at eight months.

Description

BACKGROUND OF THE NEW PLANT

Our new carnation cultivar originated as a natural mutation of the carnation variety `Loncruso` (U.S. Plant Pat. No. 5,514) and was discovered by us while inspecting the commercial production of the patent variety. We were immediately attracted by the very white coloration of the blooms characterized in an unusual manner by a cast of a very light yellow color coming from the inner portions of the flower petals. We felt that the small size of the substantially pure white flower would have good commercial merit and accordingly we propagated this sport by means of its cuttings with very satisfactory results in that the new plants appeared to be true reproductions of the original sport. Accordingly we directed that this new plant be propagated through several successive generations by means of cuttings of the next previous growth, which demonstrated that the distinctive characteristics of the original mutation would hold true from generation to generationand appeared to be firmly fixed.

DESCRIPTION OF THE DRAWING

Our new carnation cultivar is illustrated by the accompanying photographic drawing which shows, in full color, the upper portion of a typical spray stem bearing buds and blooms in various stages of development, the colors shown being as nearly true 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 observation of greenhouse grown plants made at La Londe, Les Maures, France, early in 1986, the color designations being according to The R.H.S. Colour Chart published by The Royal Horticultural Soceity of London, England.

This new spray carnation variety differs from `Loncruso` (U.S. Plant Pat. No. 5,514), the parent plant, by its overall substantially white coloration with its light yellow case from the inner center portion of the flower and its lack of the red and red-purple marginal spotting very noticeable in the flowers of the parent variety.

Claims
