Carnation named Londonie

Abstract

A new red spray carnation cultivar particularly distinguished by its relatively small flowers, borne on relatively short and rather thin but erect stems, which bloom profusely during the midseason of its Spring and Fall blooming seasons. This plant has a vigorous, upright growth habit with abundant foliage, a very branched habit, and a height averaging about 99 cm. at eight months. A particular advantage of this new plant is that it is very resistant to Fusarium oxysporum as observed INRA, Antibes, Alpes-Maritimes, France.

Description

BACKGROUND OF THE NEW PLANT

This new carnation cultivar is the result of breeding efforts carried on by us at La Londe, Les Maures, France, since 1975, with the object of developing a red spray carnation having good quality of flower and growth habit and a strong resistance to Fusarium oxysporum and in this last respect in particular, we believe we have been successful. This new plant originated as a seedling produced from our crossing of selected and individually identified plants growing among our stock of spray carnations maintained at La Londe for breeding purposes. This particular seedling was selected by us for propagation and test because it appeared to be the best of the seedlings produced by the said crossing, especially resistant to Fusarium oxysporum disease, and the discovery plant was reproduced by us at La Londe, by means of cuttings. The resulting plants appeared to be so favorable that propagation was carried on for several years through many generations, which demonstrated that the distinctive and most desirable characteristics of the discovery plant were fully retained from generation to generation and 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, a typical arrangement of buds and flowers in various stages of opening, the colors shown being as nearly true to those specified as is reasonably possible to obtain by conventional photographic procedures.

This new red spray carnation most resembles the variety "Lonsoury" and differs from "Lonsoury" by having less serration of the petals, a shorter stem and a more abundant foliage. Also, it is more resistant to Fusarium oxysporum than "Lonsoury".

Claims

1. A new and distinct spray carnation, substantially as herein shown and described, characterized by the bright red color of its small blooms borne on thin, erect stems, a vigorous growth habit with abundant foliage, and a habit of blooming profusely during its Spring and Fall flowering seasons.
