Standard carnation named Rimini

Abstract

A new and distinctive standard carnation cultivar particularly distinguished by its very large size flowers having an irregularly serrated edge. The petals are red with a greenish base. The flowers are carried on erect, thick stems, with a broad bell-shaped calyx.

Description

BACKGROUND OF THE NEW PLANT

This standard carnation cultivar originated as a hybrid seedling produced at San Remo, Italy by my crossing of two plants, hereinafter identified, selected from a field of various carnation varieties maintained at the nursery for breeding purposes. This particular seedling was selected from those produced by the said crossing because of the very unusual flower coloration on a plant having abundant foliage, favorable growth characteristics and resistance to Fusarium oxysporum. After isolation of the selected plant, vegetative propagation was made by cuttings or by in vitro culture. The said propagation was made at our laboratory located in Le Pradet, France. The new variety most resembles Lontarion (U.S. Plant Pat. No. 5,435). Rimini differs from Lontarion in a less fine and less regular serration of petals, a larger flower, a larger and wider calyx and a thicker stem. Under my direction, propagation was done by means of cuttings. The initial success of the propagation was continued through several successive generations which proved that the new variety retained all of the distinguished characteristics hold true from generation to generation and appear to be firmly fixed.

DESCRIPTION OF THE DRAWINGS

My new carnation cultivar is illustrated by the accompanying photographic drawing which, in full color, shows the form and coloration of the flowers as they appear. The colors shown are as nearly true to these herein specified as is reasonable possible to obtain by conventional photographic procedures.
