Geranium named Klegarbo

Abstract

A new geranium cultivar particularly distinguished by its round shape and compact growth, early appearing pink flowers in an upright cluster over medium-green foliage with good precocity and floral richness.

Description

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of geranium, botanically known as Pelargonium zonale-Hybride. The new cultivar is propagated from cuttings resulting from the cross of Diva and D-316. Diva is a pink colored geranium having semi-double flowers which grows very compact. Diva is not commercially available and is not known by any synonyms. D-316 is a light violet colored geranium also having semi-double flowers and does not grow very compact. D-316 is not commercially available and is not known by any synonyms. Neither Diva or D-316 has been patented. As a result of this cross the present cultivar was created in 1989 in Stutgart, Germany and has been repeatedly asexually reproduced by cuttings in Stuttgart, Germany and Teneriffe, Italy over a four year period. It has been found to retain its distinctive characteristics through successive propagations; and this novelty appears to be firmly fixed.

DESCRIPTION OF THE DRAWING

This new geranium plant is illustrated by the accompanying photographic drawing which shows blooms, buds, and foliage of the plant in full color, the color shown being as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of this new geranium. The data which defines these characteristics was collected from asexual reproductions carried out in Stuttgart, Germany. The plant history was taken on 10 week old plants, blossomed under natural light in a greenhouse. Color readings were taken in the greenhouse under ambient light. Color references are primarily to The R.H.S. Color Chart of The Royal Horticultural Society of London.

THE FLOWER

Blooming habit: Continuous and profusely from April until October.

Size: Approximately 42-44 mm.

Borne: In a cluster having between about 60-70 florets per cluster.

Form: Cup.

Pattern.--At least two of the top mature petals of each floret variably express a pattern which includes a red, blush-like spot in the central portion of the petal which effuses or bleeds, progressively into the predominant light purple color of the top surface of the margin. The spots are separated from the attachment points of these petals by a generally white, basal zone of substantially white color, except for the veins, which have the same color as the spot and from striations communicating the spot to the petal attachment points. These markings may be wholly or partly obscured by the overlying petaloids do not express similar color markings. The pattern described above is close to the center of the floret and is partly mashed by the petaloids.

Texture.--Soft.

Appearance.--Satiny.

How long do petals remain on stem: About five-seven days depending on the weather.
