Spray carnation named Lonbankir

Abstract

A new cultivar of spray carnation particularly distinguished by the medium ized, well formed flowers of a light purple coloration produced profusely in the Spring, midseason and Fall, the plant being very branched with a vigorous, upright growth habit and very abundant foliage; the plant is also very resistant to Fusarium oxysporum.

Description

BACKGROUND OF THE NEW PLANT

This new variety of spray carnation originated as a seedling of a hybrid resulting from our crossing of selected carnation varieties from our collection of carnation plants maintained at our nursery at 83250 La Londe-Les-Maures, France, our objective being to develop a spray carnation having nice color, excellent quality and a strong resistance to Fusarium oxysporum. This particular seedling was selected for propagation because of the pleasing color of its flower and the excellent quality of its growth. The selected plant was propagated by us at La Londe by means of cuttings with such pleasing results that propagation was continued through several successive generations by cuttings of successive plants, which demonstrated conclusively that the novel characteristics of the selected seedling were fully retained from generation to generation and appeared to be firmly fixed. Present propagation of this new spray carnation is done at La Londe both by cuttings and by in vitro propagation methods.

DESCRIPTION OF THE DRAWING

Our new variety of spray carnation is illustrated by the accompanying drawing, which shows several blooming stems bearing flowers in several stages of development, including a face view of a mature bloom, the colors shown being as nearly true to those herein specified as is reasonably possible to obtain by professional photographic procedures.

DESCRIPTION OF THE NEW PLANT

The following is a detailed description of our new variety of spray carnation plant made by observation of plants grown, both under glass and outdoors, at our nursery at La Londe, with color designations according to The R.H.S. Colour Chart published by The Royal Horticultural Society at London, England.
