Verbena plant named ‘Sunvivare’
Disclosed herein is a new and distinct variety of broadly spreading Verbena plant having a semi-erect growth habit with medium stems. The new Verbena plant has abundant branching particularly with respect to primary branching, and great profusion of blooms with the entire plant remaining in bloom for a considerable period of time. The flowers are large and the petals display a deep red color without an eye. The flowers are formed in profusion in a spike. The blooming period is from late April to November and the flowering duration is long. The plant exhibits high tolerance to cold, moderate tolerance to heat, high resistance to pests and diseases, particularly powdery mildew, and high resistance to rain.

Botanical/commercial classification: Verbena peruviana/Verbena Plant.
Varietal denomination: cv. ‘Sunvivare’.
BACKGROUND OF THE VARIETYThe present invention relates to a new and distinct variety of Verbena plant obtained as a mutation of Verbena peruviana variety ‘Sunvivaro’ (U.S. Plant Pat. No. 13,724, filed Nov. 16, 2001).
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 abundant branching, many deep red flowers in a spike, a long flowering duration, and a high resistance to cold, rain, diseases and pests. Accordingly, this invention is aimed at obtaining a new variety having much branching, many flowers in a spike, a long flowering duration, a high resistance to cold, rain, diseases and pests, and moderate resistance to heat.
The new variety was discovered as a spontaneous branch mutation in August 1998 while growing in a field in Germany. The mutant Verbena plant was propagated by the use of cuttings and was grown in trials beginning in May 1999 in the Yamanashi and Shiga prefectures of Japan. The botanical characteristics of the plant were examined, using a similar ‘Sunvivaro’ variety and the ‘Sunvivapa’ variety (U.S. Plant patent application Ser. No. 09/987,811, filed Nov. 16, 2001) for comparison. As a result, it was concluded that this Verbena plant is distinguishable from other varieties whose existence is known to us. The new variety of the present invention has been named ‘Sunvivare’.

This new variety of Verbena plant ‘Sunvivare’ was asexually reproduced by the use of cuttings at Youkaichi-shi, Shiga-ken, Japan and Kitakoma-gun, Yamanashi-ken, Japan, and the homogeneity and stability thereof were confirmed. The new variety has been found to reproduce true to type in subsequent generations when asexually reproduced.
SUMMARY OF THE VARIETYThis new Verbena variety has a semi-erect growth habit and is tall. The plant has much branching and an abundant number of flowers in a spike with a great profusion of blooms. The blooming period is from late April to November, the flowers commonly remain open in the rainy season, and the flowering duration is long. The entire plant remains in bloom for a considerable period of time. The flower size is large and the petal color of the flowers is deep red in the absence of an eye. The plant is highly tolerant to cold, moderately tolerant to heat, and has high resistance to pests and diseases, particularly powdery mildew, and high resistance to rain.
It commonly takes approximately 12 weeks to produce a finished plant of the new variety following the rooting of a cutting.
