Abstract

A geranium plant named Gemini having white to red flower color, startel flower type with strong divided petals; novel; decorative zonal foliage; compact growth habit with good branching; very early response; and heavy flower yield.

Description

The present invention comprises a new and distinct cultivar of geranium, botanically known as Pelargonium zonale, and hereinafter referred to by the cultivar name Gemini.

Gemini is a product of a planned breeding program which had the objective of creating new geranium cultivars having novel startel flower type and unique leaf shape.

Gemini was originated from a hybridization made by Ingeborg Schumann in a controlled breeding program in Hillscheid, Federal Republic of Germany in 1978. The female parent was an inbred line from H42 and Stellar Artic Star. The male parent of Gemini was Stellar Orange. Both parents are unpatented.

Gemini was discovered and selected as one flowering plant within the progeny of the stated cross by Ingeborg Schumann on July 7, 1979 in a controlled environment in Hillscheid, Federal Republic of Germany.

The first act of asexual reproduction of Gemini was accomplished when vegetative cuttings were taken from the initial selection in January of 1980 in a controlled environment in Hillscheid, Federal Republic of Germany by a technician working under formulations established and supervised by Ingeborg Schumann. Horticultural examination of selected units initiated in the spring of 1980 and continuing in 1981 through 1983 has demonstrated that the combination of characteristics as herein disclosed for Gemini are firmly fixed and are retained through successive generations of asexual reproduction.

Gemini has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, and day length. The following observations, measurements and comparisons describe plants grown in Hillscheid, Federal Republic of Germany, under conditions which approximate those generally used in commercial practice.

The following traits have been repeatedly observed and are determined to be basic characteristics of Gemini, which in combination distinguish this geranium as a new and distinct cultivar.

1. Red and light pink to white flowers having star shaped petals; divided petals are strong.

2. Novel leaf shape; very decorative.

3. Compact habit with good branching.

4. Very early flowering.

5. Heavy flower yield in spring and summer.

The accompanying photographic drawings shows typical flower and foliage characteristics of Gemini, with colors being as true as possible with illustrations of this type. Sheet 1 is a color photograph showing Gemini in perspective view. Sheet 2 is a black and white print showing the novel leaf shape of Gemini, at three stages of growth.

In the following description color references are made to The Royal Horticultural Society Colour Chart. The color values were determined between 2:00 p.m. and 3:00 p.m. on May 15, 1985 under 20,000 Lux light intensity at Hillscheid, Federal Republic of Germany.
