Geranium named Markoni

Abstract

A new variety of geranium plant particularly distinguished by its profuse production of flowers having a nice, somewhat brick red color, the individual florets having the form of a cup with six to nine imbricated petals, and about sixty-five of these florets together forming a delicate cluster which stands on a flower stem of about 17 cm. long and extending upwardly from a strong, upright stalk of about 23 to 25 cm. in length. The foliage of this plant is well formed and contains a moderate amount of green leaves that are of medium to small size, the foliage body standing about 20 cm. above the soil. This new plant is an early blooming variety resistant to heat and rain, as well as to botrytis, and for these reasons, seems to be an ideal variety for mass production for the general market.

Description

BACKGROUND OF THE NEW PLANT

This new geranium plant originated as a seedling of a hybrid resulting from my crossing in 1985 of unnamed plants, growing in my nursery at Stuttgart, West Germany, with the primary object of seed collection. This particular seedling was selected for propagation because of its attractive flower coloration, its profuse production of flowers, and its early blooming habit. Propagation of this particular seedling by means of cuttings from the parent plant was done by me and under my direction at Stuttgart with very satisfactory results and such propagation was carried on at Stuttgart through several successive generations, which demonstrated clearly that the novel and advantageous characteristics of the new plant were fully retained from generation to generation and appeared to be firmly fixed, thus assuring its homogeneity.

DESCRIPTION OF THE DRAWING

This new geranium plant is illustrated by the accompanying full color photographic drawing, which shows the flower form, bud clusters in several stages of development, and the character of the foliage of this plant, the color shown being as true to that herein specified as is reasonably possible to obtain by conventional, professional photographic procedures.

DESCRIPTION OF THE NEW PLANT

The following is a detailed description of my new geranium cultivar based upon observation made in the Fall of 1987 of plants of this variety grown in greenhouse, as well as outdoors, the color designations being according to The R.H.S.
