Verbena plant named ‘Sunmaricos’

Abstract

Disclosed herein is a new and distinct variety of Verbena plant having a spreading growth habit and long stems. The plant forms flowers in clusters with a great profusion of blooms. The blooming period commonly is from late April to November and the flowering duration is long. Accordingly, the entire plant remains in bloom for an extended period of time. The flower size is large and the petal color of the flowers is deep purplish pink. The plant is highly tolerant to heat, and exhibits a high resistance to pests and diseases, particularly powdery mildew, and has a high resistance to rain.

Description

Botanical/commercial classification: Verbena hybrida/Verbena Plant.

Varietal denomination: cv. ‘Sunmaricos’.

BACKGROUND OF THE VARIETY

The present invention provides a new and distinct variety of Verbena×hybrida plant obtained from the open-pollination of the ‘114-7’ variety (non-patented in the United States). The identity of the male parent is unknown. The ‘114-7’ variety was developed from crossing a Verbena hybrida plant named ‘Amethyst’ (non-patented in the United States) as female and an unnamed and non-patented wild type of Verbena peruviana plant native to Brazil as male.

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 Verbena plants which have a spreading growth habit, abundant branching, many flowers in a cluster, and a high resistance to rain, heat, cold and diseases. Accordingly, this invention is aimed at obtaining a new variety having a spreading growth habit, abundant branching, a large number of deep purplish pink flowers in a cluster having a large diameter, and a high tolerance to heat and cold, and resistance to diseases and pests.

In August 1997, seedlings resulting from open-pollination of the ‘114-7’ variety were obtained at Torihara, Hakushu-cho, Kitakoma-gun, Yamanashi-ken, Japan. In January 1998, a seedling was selected in view of its spreading growth habit, less bluish and more reddish pigment in the flower than its parent and deep purplish pink petals. Such selection was propagated by the use of cuttings, and was evaluated in flowerbeds and planters beginning in April 1998 at Torihara, Hakushu-cho, Kitakoma-gun, Yamanashi-ken, Japan, and at Aza-Iketani, Omori-cho, Yokaichi-shi, Shiga-ken, Japan. The botanical characteristics of the plant were examined using the similar varieties ‘SUNVP-PI’ (U.S. Plant Pat. No. 10,705) and ‘Surimarisa’ (U.S. Plant Pat. No. 11,130) for comparison. As a result, it was concluded that the subject Verbena plant is distinguishable from other varieties whose existence is known to me and is uniform and stable in its characteristics. This new variety was named ‘Sunmaricos’.
