Abstract

A new variety of spray carnation having a recurrent blooming habit and a profuse production of small, clear white blooms during the spring, midseason and fall intervals, the blooms appearing in clusters at the upper portion of a strong, erect stem and the plant itself being distinguished by its relatively tall growth and its vigorous, upright and rather rigid growth habit with abundant foliage.

Description

BACKGROUND OF THE NEW PLANT

This new carnation variety originated as a seedling resulting from our crossing of selected plants from our collection of carnations maintained for breeding purposes at La Londe, Les Maures, France. Our object in making this crossing was to develop a spray carnation having blooms of nice color on a plant having good quality of flower, spray, stem and growth habit, as well as resistance to Fusarium oxysporum. This selected plant was reproduced by cuttings at La Londe with such pleasing results that propagation was continued at La Londe by both cuttings and in vitro through several successive generations, which clearly demonstrated that the novel and advantageous characteristics of this new variety appeared to be firmly fixed and would hold true from generation to generation.

DESCRIPTION OF THE DRAWING

This new variety of spray carnation is illustrated by the accompanying photographic drawing which shows, in full color, the upper portion of a typical spray stem bearing buds in various stages of opening and flowers at several stages of maturity, the colors shown being as nearly true to that specified herein as 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 plants grown at La Londe, Les Maures, France, in the spring of 1986, the color designations being according to the R.H.S. Colour Chart published by The Royal Horticultural Society of London, England.

THE PLANT

Origin: Seedling.

Parentage:
