ABSTRACT:
BOTANICAL/COMMERCIAL CLASSIFICATION
Verbena peruviana
/Verbena Plant.
VARIETAL DENOMINATION
cv. ‘Sunvivaro’.
BACKGROUND OF THE VARIETY
The present invention relates to a new and distinct variety of Verbena plant obtained from crossing a wild type of Verbena plant
Verbena peruviana
(♀) native to Brazil and another wild type of Verbena plant
Verbena peruviana
(♂) native to Brazil.
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 Verbena plants having much branching, many flowers in a spike, a long flowering duration and which have a high resistance to rain, heat, cold, and disease. Accordingly, this invention was aimed at obtaining a new variety having an erect growth habit, strong branching, many flowers in a spike, long flowering duration, high tolerance to heat and cold, and resistances to diseases and pests, and also having petals that are vivid purplish red.
The new variety of Verbena plant according to this invention originated from crossing of a wild type of Verbena plant
Verbena peruviana
(♀) native to Brazil and another wild type of Verbena plant
Verbena peruviana
(♂) native to Brazil.
First of all, 32 seedlings were obtained in the autumn of 1993, from crossing a wild type of Verbena plant ‘VBA’ (
Verbena peruviana
f. rosea—non-patented in the United States) as female parent and another wild type of Verbena plant ‘VBB’ (
Verbena peruviana
f. rosea—non-patented in the United States) as pollen parent in the spring of 1993. From this crossing, one seedling was selected in view of erect growth habit, branching and petal color, and propagated by cutting, and then grown as a trial in flower beds and planters from the spring of 1994. Finally a trial by flower potting and bedding was carried out on the selected one plant to the autumn of 1995. The botanical characteristics of the selected one seedling were examined, using similar varieties ‘Sunvivapa’ (Appl. No. 8239 under the Seeds and Seedlings Law of Japan and U.S. Plant patent application No. 09/987,811, filed Nov. 16, 2001) and ‘Showtime Blaze’ (non-patented in the United States) for comparison. As a result, it was concluded that this Verbena is distinguishable from any other variety whose existence is known to us, and is uniform and stable in its characteristics. This new variety of Verbena plant was named ‘Sunvivaro’.
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-National Bureau of Standards 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 female parent ‘VBA’ and the pollen parent ‘VBB’, used in the obtaining of this new variety ‘Sunvivaro’, are wild types of Verbena native to South Brazil.
The new variety of the present invention can be readily distinguished from its ‘VBA’ and ‘VBB’ parental varieties. More specifically, the new variety forms vivid purplish red flowers and the parental varieties each form blue flowers.
The ‘Showtime Blaze’, used as a comparison for this new variety ‘Sunvivaro’, is commercially available. The petal color of ‘Showtime Blaze’ is similar to that of ‘Sunvivaro’. The main botanical characteristics of ‘Showtime Blaze’ are as follows:
