The present invention relates to a new and distinct variety of verbena plant obtained from crossing of the verbena plant (.female.) which was obtained from crossing "Cristal" (.female.) and a wild type of verbena plant Verbena peruviana native to Brazil (.male.), and the same wild type of verbena plant Verbena peruviana (.male.) native to Brazil.
The verbena 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 verbena plant which have a spreading growth habit, much branching, the formation of a high number of flowers in a spike and which have a high resistance to rain, heat, cold, and diseases. Accordingly, this invention was aimed at obtaining a new variety having a spreading growth habit, strong branching, the formation of a high number of flowers in a spike, a large diameter flower, high tolerance to heat and cold, and resistance to diseases and pests, and also having yellowish white flower petals.
The new variety of verbena plant according to this invention originated from crossing of the verbena plant (.female.) which was obtained from crossing Verbena hybrida "Cristal" (.female.) and a wild type of verbena plant Verbena peruviana native to Brazil (.male.), and the same wild type of verbena plant Verbena peruviana (.male.) native to Brazil. The new variety of the present invention is botanically classified Verbena hybrida.
First of all, 4 seedlings were obtained in the autumn of 1992, from crossing "CRISTAL" as female parent and a wild type of verbena plant (Verbena peruviana) as pollen parent in the May of 1992. These 4 seedlings were grown and the 3 seedlings were selected in view of spreading growth habit and flower petal coloration. Then 12 seedlings were obtained from crossing these 3 seedlings as female parent and the same wild type of verbena plant (Verbena peruviana) as pollen parent. These 12 seedlings were grown and the 4 seedlings were selected in view of spreading growth habit and flower petal coloration. And these selected 4 seedlings ware propagated by the use of cuttings, and then grown as a trial for flower bedding and planter growth beginning in the spring of 1993. Finally only one plant was selected from these 4 seedlings during such evaluation that was carried out until the autumn of 1994 and the botanical characteristics of 4 seedlings were examined, using the similar variety "Cristal" for comparison. As a result, it was concluded that this verbena is distinguishable from any other variety whose existence is known to us, is sufficiently uniform and is stable in its characteristics. This new variety of verbena plant was named "Sunmariho".
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. Color 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 "Cristal" plant used as female parent in the crossing which resulted in the formation of this new variety "Sunmariho" variety is commercially available. The main botanical characteristics of "Cristal" are as follows.
Plant: PA0 Stem: PA0 Leaf: PA0 Flower: PA0 Physiological and ecological characteristics: Low resistance to diseases and pests, low tolerances to heat, cold and rain. PA0 Plant: PA0 Stem: PA0 Leaf: PA0 Flower: PA0 Physiological and ecological characteristics: High resistance to diseases and pests, high tolerances to heat, cold and rain.

The pollen parent used in the crossing which was obtained to this new variety "Sunmariho" was a wild type of verbena native to South Brazil and Verbena peruviana. This wild type of verbena plant is presently maintained at the Plant Biotechnology Laboratory of Suntory Ltd., residing at 863-1, Aza-Iketani, Oomori-cho, Youkaiti-shi, Shiga-ken, Japan.. The main botanical characteristics of this pollen parent are as follows.
This new variety of verbena plant "Sunmariho" was asexually reproduced by cuttings at the Plant Biotechnology Laboratory of Suntory Ltd., 863-1, Aza-Iketani, Oomori-cho, Youkaiti-shi, Shiga-ken, Japan, and the homogeneity and stability thereof were confirmed.
