The present invention relates to a new and distinct variety of torenia plant obtained from the mutant of "Sunrenibu" which was obtained from crossing of "Crown Mix" (.female.) and "Con Color" (.male.).
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, a high resistance to heat and diseases. And the torenia plant needs full sunshine and hardly grows and has flowers in the shade of trees. Accordingly, this invention was aimed at obtaining a new variety having a great profusion of flowers, very big flower, light purple, deep purple and vivid purple bi-color flower petal with light purple floral tube, semi-erect growth habit, a high resistance to heat and diseases, and growing and having flowers ordinarily in the shade of trees.
The new variety of torenia plant according to this invention originated from the mutant of a spontaneously generic variant of "Sunrenibu" (U.S. Application. Ser. No. 559,853) which we previously filed. The new variety of torenia plant was discovered in view of large diameter flower during propagation of "Sunrenibu" in April, 1995. The discovered torenia plant was propagated by cutting from summer, 1995 and then grown in bed and pot on trial from summer, 1995 at the Hakushu Nursery Center of SUNTORY Ltd., residing at 2913-1 Torihara, Hakushu-cho, Kitakoma-gun, Yamanashi-ken, Japan. The botanical characteristics of the plant was examined, using parent variety, "Sunrenibu" and the similar variety "Crown Violet", for comparison. As a result, it was concluded that this discovered torenia plant is distinguishable from any other variety, whose existence is known to us, sufficiently uniform and stable in its characteristics, then this new variety of torenia plant was named "Sunrenilabu".
In the following description, the color-coding is in accordance with The Horticultural Colour Chart of The Royal Horticultural Society, London, England (R.H.S. Colour Chart), and the Inter-Society color Council-Nation Bureau of Standard Color Name (I.S.C.C.-N.B.S. Color Name). A color chart based on The Japan Color Standard for Horticultural Plant (J.H.S. Color Chart) is also added for reference.
The mutant parent variety "Sunrenibu" of this new variety "Sunrenilabu" is presently planted and maintained at the Hakushu Nursery Center of SUNTORY Ltd., residing at 2913-1 Torihara, Hakushu-cho, Kitakoma-gun, Yamanashi-ken, Japan. The main botanical characteristics of "Sunrenibu" are as follows.
