A new spray carnation cultivar particularly distinguished by its profuse duction of small light pink flowers of a China Rose and Neyron Rose coloration borne on strong, upright stems. This plant has a vigorous, upright and rather rigid growth habit with abundant foliage and a height averaging about 95 cm. at eight months.

Description
BACKGROUND OF THE NEW PLANT

Our new spray carnation cultivar is the result of breeding efforts carried on by us at La Londe, Les Maures, France, since 1978 with the object of developing a spray carnation of nice color and good quality of flower and plant growth and particularly a resistance to Fusarium oxysporum. This new plant originated as a seedling produced from our crossing of selected and individually identified plants growing among our stock of spray carnation plants maintained at La Londe for breeding purposes. This particular seedling was selected by us for propagation and test because of its nice flower color, profuse production of blooms and its resistance to Fusarium oxysporum, and this discovery plant was reproduced by us at La Londe, by means of cuttings. The result of that propagation effort appearing to be very favorable with respect to retention of the novel characteristics of the parent plant, its propagation was continued under our direction through several successive generations, which established that the novel and distinctive 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 spray showing buds and flowers in various stages of opening, the colors shown being as nearly true to those herein specified as is reasonably possible to obtain by conventional photographic procedures.
