Geranium plant named Marktex

Abstract

A new and distinctive geranium cultivar particularly distinguished by its very large flower clusters, or flower balls, of a light red or vermilion coloration and comprising up to about sixty closely-growing florets of medium size, each with five very broad, imbricated petals. The cluster stalks are sturdy, upright, brown in color and about 12 cm. long and the blooms are very long lasting. The foliage is bushy and abundant, the medium sized leaf having an intensive zonation, and the foliage extends about 15 cm. above the soil.

Description

BACKGROUND OF THE NEW PLANT

This new geranium cultivar originated as a seedling of a random pollinated variety named `Osna` (unpatented) being grown in my nursery at Stuttgart, West Germany, with the object of seed collection. The present variety was selected for propagation from a group of seedlings of `Osna` because of the very large size and light red coloration of its flower clusters, which comprise about sixty closely-growing florets, the petals of which have a pleasing red body color and lightly colored marginal edges; and because of its abundant, sturdy foliage of dark green, medium sized leaves which offset the color intensity of the flowers, propagation of this selected plant was carried on by me and under my direction by means of cuttings at Stuttgart with such success that propagation was continued at Stuttgart in the same manner through several successive generations, which demonstrated conclusively that the distinctive characteristics of the selected plant would hold true from generation to generation and appeared to be firmly fixed. This new plant is now being propagated by means of cuttings for commercial purposes at Stuttgart.

DESCRIPTION OF THE DRAWING

My new geranium cultivar is illustrated by the accompanying photographic drawing which, in full color, shows several clusters of florets and buds with the color rendition being as closely true to that herein specified as is reasonably possible to obtain by conventional, professional, photographic procedures.
