| Abstract: |
A geranium plant named Columbia having red flowering startel flower type with strong divided petals; novel, decorative zonal foliage; compact growth habit with good branching; and heavy flower yield. |
| Claim: |
I claim:
1. A new and distinct cultivar of geranium named Columbia, as described and illustrated, and particularly characterized by its red flowering startel flower type, with strong dividedpetals; novel, decorative zonal foliage; compact growth habit with good branching; and its 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 Columbia.
Columbia is a product of a planned breeding program which had the objective of creating new geranium cultivars having novel flower startel type and unique leaf shape.
Columbia 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 H43 and Stellar Artic Star. The male parent ofColumbia was Stellar Orange. Both parents are unpatented.
Columbia was discovered and selected as one flowering plant within the progeny of the stated cross by Ingeborg Schumann on June 13, 1979 in a controlled environment in Hillscheid, Federal Republic of Germany.
The first act of asexual reproduction of Columbia 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 workingunder formulations established and supervised by Ingeborg Schumann. Horticultural examination of selected units initiated in the spring of 1980 and continued in 1981 through 1983 has demonstrated that the combination of characteristics as hereindisclosed for Columbia are firmly fixed and are retained through successive generations of asexual reproduction.
Columbia 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 andcomparisons 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 Columbia, which in combination distinguish this geranium as a new and distinct cultivar.
1. Red flowers with startel flower type; divided petals are strong.
2. Novel leaf shape; generally star shaped; very decorative.
3. Compact habit with good branching.
4. Early response and heavy flower yield in spring and summer.
The accompanying photographic drawings shows typical flower and foliage characteristics of Columbia, with colors being as true as possible with illustrations of this type.
Sheet 1 is a color photograph showing Columbia in perspective view.
Sheet 2 is a black and white print showing the novel leaf shape of Columbia, at three stages of growth.
In the following description color references are made to The Royal Horticultural Society Colour Chart. The color values aredetermined 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.
