Carnation named Lonpindi

Abstract

A new variety of carnation plant particularly distinguished by the substantially white coloration of its medium sized blooms which are borne singly on relatively long stems of erect and rigid character, its vigorous and upright growth habit, abundant foliage, and its resistance to Fusarium oxysporum.

Description

BACKGROUND OF THE NEW PLANT

This new carnation cultivar originated as a sport of the variety "Londorga" (U.S. Plant Pat. No. 5,784) being grown at 83250 La Londe, Les Maures, France, this sport having been discovered in 1982 and propagated by us with cuttings for testing and evaluation because of its unusual yellowish white color and its red striations at the petal tips. This initial propagation appeared to be so satisfactory that continued propagation through successive generations, by both cuttings and in vitro procedures, demonstrated conclusively that the new plant retained all of the distinguishing characteristics of the original natural mutation and that these characteristics hold true from generation to generation and appear to be firmly fixed.

DESCRIPTION OF THE DRAWING

This new carnation cultivar is illustrated by the accompanying photographic drawing which shows a three-fourths top view of a group of flowers in several stages of maturity, the color rendition 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 cultivar based upon observation of plants grown in Southern France during the current year, the color designations being according to The R.H.S. Colour Chart published by The Royal Horticultural Society of London, England.

In general, the characteristics of this plant may be more-or-less strongly modulated according to environmental conditions, method of cultivation, and latitude where grown. In general, this new carnation cultivar is similar to the variety "Londorga" but has a yellowish white color and is red striated at its outer end margin.

Claims
