ABSTRACT:
Botanical/commercial classification:
Verbena calliantha
/Verbena Plant.
Varietal denomination: cv. ‘Sunmaref TP-SAP’.
BACKGROUND OF THE VARIETY
The present invention relates to a new and distinct variety of
Verbena calliantha
plant obtained by crossing a wild type of verbena plant
Verbena calliantha
f. rosea (♀) native to Brazil and the ‘Rainbow Carpet Red’ (♂) variety (non-patented in the United States) and botanically known as Verbena×hybrida Voss.
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, a large number of flowers in clusters and 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, a large number of flowers in clusters, high tolerance to heat, rain, drought and cold, and resistance to diseases and pests combined with a strong purplish pink petal coloration.
Initially, 35 seedlings were obtained from the crossing in March of 1996. One seedling was selected in view of its spreading growth habit and flower color. The seedling was propagated by the use of cuttings. The resulting plants were tested while growing as potted and bedding plants from the spring of 1997 to the autumn of 1998 and the botanical characteristics were compared to those of the ‘Flower Carpet Red’ variety. As a result, it was concluded that this verbena plant 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 ‘Sunmaref TP-SAP’.
In the following description, the color-coding is in accordance with the chart of The Royal Horticultural Society, London, England (R.H.S. Colour Chart). The color chart based on The Japan Color Standard for Horticultural Plants (J.H.S.. Color Chart) is also added for reference.
The female parent used in the obtaining of this new variety ‘Sunmaref TP-SAP’ was a wild type of verbena (
Verbena calliantha
) native to South Brazil that was introduced to Japan in 1995. This wild type of verbena plant is presently maintained in Japan. The main botanical characteristics of this female parent are as follows:

This new variety of verbena plant named ‘Sunmaref TP-SAP’ was asexually reproduced by the use of cuttings at the Hakusyu Research Center of SUNTORY Ltd., located at 2913-1 Torihara, Hakusyu-cho, Kitakomagun, Yamanashi-ken, Japan, and the homogeneity and stability thereof were confirmed.
SUMMARY OF THE NEW VARIETY
This new variety of verbena plant has a broad spreading growth habit, and forms long stems. The plant has abundant branching and forms a large number of flowers in clusters with a great profusion of blooms. The blooming period is April to November and flowering duration is long with the entire plant remaining in bloom for a considerable period of time. The flower size is medium and the petal color of the flower is strong purplish pink. The plant is highly tolerant to cold, heat, rain and drought and displays a high resistance to pests and diseases, particularly to powdery mildew.
