Verbena plant named ‘Sunmariro’
Disclosed herein is a new and distinct variety of a broadly spreading Verbena plant. The new Verbena plant has abundant branching particularly with respect to primary branching, and a 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 vivid red color without an eye. The flowers are formed in profusion in a spike. The blooming period is from early April to November, and the flowering duration is long. The plant exhibits high tolerance to cold and heat, high resistance to pests and diseases, particularly powdery mildew, and high resistance to rain.

Botanical/commercial classification: Verbena hybrida/Verbena Plant.
Varietal denomination: cv. ‘Sunmariro’.
BACKGROUND OF THE VARIETYThe present invention relates to a new and distinct variety of Verbena plant obtained from a crossing of Verbena plant variety Verbena hybrida ‘H39-2’ (non-patented in the United States) and the same Verbena hybrida ‘H39-2’.
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, abundant branching, many flowers in a spike, and a high resistance to heat, cold, and diseases. Accordingly, this invention is aimed at obtaining a new variety having a spreading growth habit, much branching, many flowers in a spike, vivid red flowers having a large diameter, high tolerance to heat and cold, and resistance to diseases and pests.
The variety ‘H39-2’ (non-patented in the United States) was obtained from the open-pollination of the Verbena variety ‘135-2’ and an unknown Verbena plant. Seedlings were obtained in the July of 1997, from crossing ‘H39-2’ as the female parent and the same Verbena plant, and were grown from the September of 1997 at Kitakoma-gun, Yamanashi-ken, Japan. Among these plants, one was selected in view of its spreading growth habit and petal color, and was propagated by use of cuttings, and then was evaluated beginning in January 1998. The botanical characteristics were examined, using similar ‘SUNVP-PI’ (U.S. Plant Pat. No. 10,705) for comparison. As a result, it was concluded that this new Verbena variety is distinguishable from any other variety whose existence is known to me and is uniform and stable in its characteristics. This new variety was named ‘Sunmariro’.
