ABSTRACT:
Botanical/commercial classification: Verbena hybrida×
peruviana
/Verbena plant.
Varietal denomination: cv. ‘Sunvivapa’.
BACKGROUND OF THE VARIETY
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 which is 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 a 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 reddish purple.
The new variety of Verbena plant according to this invention originated from crossing a Verbena hybrida ‘Showtime Blaze’ (♀) (non-patented in the United States), and a wild type of Verbena plant
Verbena peruviana
‘VBC’ (♂) (non-patented in the United States) native to Brazil.
Initially, 45 seedlings were obtained in the autumn of 1992 from crossing of Verbena hybrida ‘Showtime Blaze’ as female parent and a wild type of Verbena plant ‘VBC’ (
Verbena peruviana f. rosea
) as pollen parent. From this crossing, 12 seedlings were selected in view of their erect growth habit, branching, and petal color, were propagated by the use of cuttings, and were tested in flower beds and planters from in the spring of 1993 to the autumn of 1994. The botanical characteristics of 12 seedlings were examined and only one seedling was selected, using parent varieties ‘Showtime Blaze’ and ‘VBC’ for comparison. As a result, it was concluded that this selected Verbena is distinguishable from any other varieties whose existence is known to us, and is uniform and stable in its characteristics. This new variety of Verbena plant was named ‘Sunvivapa’.
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). A color chart based on The Japan Color Standard for Horticultural Plant (J.H.S. Color Chart) is also added for reference.

The new variety of Verbena plant ‘Sunvivapa’ was asexually reproduced by the use of cuttings at the aforementioned Hakushu Nursery Center of SUNTORY Ltd., residing at 2913-1 Torihara, Hakushu-cho, Kitakoma-gun, Yamanashi-ken, Japan, and the homogeneity and stability thereof were confirmed. The instant plant retains its distinctive characteristics and reproduces true to type in successive generations.
SUMMARY OF THE VARIETY
This new variety of Verbena plant has erect growth habit and a tall growth habit. The plant has many branches and abundantly forms flowers in a spike. The blooming period is late April to November and the flowering duration is long. The whole plant remains in bloom for a considerable period of time. The flower petal color is vivid reddish purple color without an eye. The plant is highly tolerant to heat, cold, and has a high resistance to pests and diseases, particularly powdery mildew, and has a high resistance to rain.
The plants described herein were approximately eight months of age and were observed during August while growing in pots. Such plants were being grown at Shimamoto-cho, Mishima-gun, Oosaka-fu, Japan. Approximately ten weeks are required to produce a finished flowering plant following the rooting of cuttings.
