Verbena plant named ‘Sunmarisakura’

- Suntory Flowers Limited

Disclosed herein is a Verbena plant having a decumbent growth habit and long stems. The plant forms flowers in clusters with a great profusion of blooms. The flowering duration is long and the entire plant remains in bloom for a considerable period of time. The flower size is large and the petal color of flowers is light purplish pink. The plant is highly tolerant to heat, pests and diseases, particularly powdery mildew, and is moderately resistant to cold. ‘Sunmarisakura’ does not freely set seed due to self-sterility.

Description

Botanical classification: Verbena hybrida.

Varietal denomination: ‘Sunmarisakura’.

BACKGROUND OF THE VARIETY

The present new distinct cultivar of Verbena was created by heavy ion beam irradiation of the Verbena hybrid variety called ‘Sunmarisa’. ‘Sunmarisa’ (U.S. Plant Pat. No. 11,130) is our Verbena hybrid variety grown at Yokaichi-shi, Shiga-ken, Japan.

In July 1998, 5Gy of ionic nitrogen (135 MeV) was irradiated onto 128 pieces of in vitro axillary bud of ‘Sunmarisa’ using the Ring Cyclotron at The Institute of Physical and Chemical Research. Two weeks later, elongated buds were grown from cuttings. In March 1999, five varieties were selected in view of self-sterility. These plants were propagated by cutting and then grown in pot and planter box on trial from May 1999 at Yokaichi-shi, Shiga-ken, Japan. Additionally, the plants were grown in pots and planter boxes during trial in 2000. Finally, one plant was selected from these five varieties in view of having a long flower duration. By November 2000, the botanical characteristics of the selected plant were examined. As a result, it was concluded that this new 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 ‘Sunmarisakura’.

The new variety of the present invention can be distinguished from its parent ‘Sunmarisa’ in its self-sterility. Also the new variety can be distinguished from the similar variety ‘Sunmaripi’ in the flower color and self-sterility.

The new variety of Verbena plant ‘Sunmarisakura’ was asexually reproduced by cutting at Yokaichi-shi, Shiga-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.

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.).

‘Sunmarisa’ was used to produce the new variety, ‘Sunmarisakura’. The botanical characteristics of ‘Sunmarisa’ are as follows when grown at Yokaichi-shi, Shiga-ken, Japan.
