ABSTRACT:
Botanical/commercial classification: Torenia hybrida/Torenia Plant.
Varietal denomination: cv. Sunrenirirepa.
BACKGROUND OF THE VARIETY
The present invention relates to a new and distinct variety of Torenia plant that was obtained as a spontaneous mutation of unknown causation of the ‘Sunrenimu’ variety (U.S Plant Pat. No. 10,120).
The Torenia is a very popular plant and is used for flower bedding and potting in the summer season. There are only a few varieties of the Torenia plant which have a semi-erect growth habit, medium branching, and a great profusion of blooms.
Accordingly, this invention is aimed at obtaining a new variety having vivid red purple flower petals without a yellow eye color, a semi-erect growth habit, medium branching, and great profusion of blooms.
The new variety of Torenia plant was discovered during January 1997 primarily on the basis of the distinctive flower color during propagation of ‘Sunrenimu’ variety at Yokaichi-shi, Shiga-ken, Japan. The new Torenia plant was propagated by the use of cuttings beginning in January 1997, and then was grown in flower beds and pots beginning in April 1997. The botanical characteristics of the plant were examined using a similar ‘Crown Violet’ variety (non-patented in the United States) and the parental variety for comparison. As a result, it was concluded that the new Torenia plant of the present invention is distinguishable from all other varieties whose existence is known to me. The new variety is uniform and stable in its characteristics has been named ‘Sunrenirirepa’.
In the following description the color-coding is in accordance with The R.H.S. Colour Chart of The Royal Horticultural Society, London, England. A color chart based on The Japan Color Standard for Horticultural Plants (J.H.S. Color Chart) is also added for reference.
The ‘Sunrenimu’ parent plant variety was obtained from crossing the ‘Crown Violet’ variety having purplish white flower petals as the female parent and the ‘Con Color’ variety having strong bluish purple flower petals as the pollen parent. This cross was carried out during February 1993 at Shimamoto-cho, Mishima-gun, Osaka-fu, Japan.
