Geranium named Klerissa

Abstract

A new and distinct geranium cultivar particularly distinguished by the intensive red coloration of its well filled blooming clusters which stand well above a compact mass of dark green foliage, thereby providing a sharp and very attractive appearance for the blooming plant. The plant itself is very bushy and is of a relatively low overall height of about 30 cm. above the soil, the growth rate being medium but upright and compact with good strength. The floral persistence is very good and the lasting quality of the blooming plant is very long from early Spring to late Fall.

Description

BACKGROUND OF THE NEW PLANT

My new geranium cultivar originated as a seedling of unknown parentage found in my nursery at Stuttgart, West Germany, among a stand of geranium varieties maintained by me for breeding purposes. This new plant was discovered in 1984 and because of its presentation of the flower clusters, well above a body of dark green leaves, this plant was selected for propagation, which was done by me and under by direction with cuttings at Stuttgart and carried on through several successive generations whereby to determine the homogeneity could be assured. Thus it was determined conclusively that the distinctive and novel characteristics of this new plant would hold true from generation to generation and appeared to be firmly fixed. The new plant is weather-proof, resistant against Botrytis, and has a substantial decoration and market value.

DESCRIPTION OF THE DRAWING

My new geranium cultivar is illustrated by the accompanying full color photographic drawing, which illustrates a potted plant showing the general character of the new variety with respect to both the foliage and flower clusters, the colors shown being as true to that specified herein as is reasonably possible to obtain by conventional, professional photographic procedures.
