Carnation named Lontoyo

Abstract

A new spray carnation variety having small, bright orange blooms produced profusely at intermittent intervals from spring through fall in clusters appearing at the upper portion of strong, upright and rigid stems, the flowers being distinguished by their relatively small size and the orange coloration of the petals, which are striated with longitudinally extending, red lines, and the plant itself being distinguished by its tall, vigorous and upright growth habit with moderately abundant foliage.

Description

BACKGROUND OF THE NEW PLANT

This new carnation variety originated as a seedling resulting from our crossing of plants selected from our collection of carnation plants maintained by us for breeding purposes at La Londe, Les Maures, France, our object in making this crossing being to develop a new spray carnation having blooms of good quality and color and having resistance to Fusarium oxysporum. Our new plant was reproduced by cuttings with such satisfactory results that further propagation was directed to be carried on through successive generations, also by means of cuttings, from previous plants of the new variety produced in the same manner. From observation of our propagation of the new seedling, we are satisfied that the novel characteristics of its blooming and growth habits would remain true from generation to generation and appear to be firmly fixed.

DESCRIPTION OF THE DRAWING

Our new variety of spray carnation is illustrated by the accompanying full color photographic drawing, which shows the upper portions of typical spray stems bearing buds and flowers at various stages of maturity, the colors shown being as nearly true to those specified herein as is reasonably possible to obtain by professional photographic procedures.

Borne: In a cluster.

Shape: When bloom first opens, high centered. When bloom matures, dome shaped.

Petalage:

Number of petals.--About 29 (in average).

Filiments.--Color: Whitish.

Pistils:

Number.--3 to 4.

Color.--Whitish.

Stigmas.--Color: Lightly pinkish.

Ovaries: Hardly ribbed.

This new spray carnation variety most nearly resembles the variety `Lonforem` (U.S. Plant Pat. No. 5,444) but differs by having a brighter color, less deeply serrated form of petals, and being smaller in flower size.
