Abstract

A new and distinct Verbena variety is provided which forms attractive medium-sized purplish pink blossoms. The plant is broad and exhibits a spreading growth habit. The blossoms are borne in abundance on spikes. The blossoming is of long duration and commonly occurs between April and November. The plant exhibits a high tolerance to rain, cold, and heat and good resistance to diseases, such as powdery mildew.

Description

BACKGROUND OF THE VARIETY

The present invention relates to a new and distinct variety of Verbena plant obtained from a crossing Vorbena×hybrida `Rainbowcarpet rose` (♀) and a wild type of Verbena plant Verbena peruviana f. rosea. (♂) native to Brazil.

The Verbena is a very popular plant and is used for flower bedding and as a pot plant in the summer season. There are only a few varieties of the verbena plant which have a spreading growth habit, much branching, the formation of a high number of flowers in a spike and which have a high resistance to rain, heat, cold, and deseases. Accordingly, this invention was aimed at obtaining a new variety having a spreading growth habit, strong branching, the formation of a high number of flowers in a spike, high tolerance to heat, rain, drought and cold, and resistance to diseases and pests, and also having strong purplish pink flower petals.

The new variety of verbena plant according to this invention originated from crossing of `Rainbowcarpet rose` (♀) and a wild type of verbena plant Verbena peruviana f. rosea. (♂) native to Brazil.

First of all, 4 seedlings were obtained from crossing Verbena×hybrida `Rainbowcarpet rose` as female parent and a wild type of verbena plant (Verbena peruviana f. rosea) as pollen parent in the May of 1992. From this crossing 1 seedling was selected in view of the spreading growth habit and flower coloration. This seedling that was selected was propagated by the use of cuttings and was grown for evaluation during which time the botanical characteristics of the seedling was examined, using the similar variety `Rainbowcarpet rose` for comparison, from in the spring of 1993 to in the autumn of 1994. As a result, it was concluded that this Verbena is distinguishable from any other variety whose existence is known to us, and is uniform and is stable in its characteristics. This new variety of Verbena plant was named `SUNMAREF TP-SP`. The new variety of the present invention is botanically classified as Verbena×hybrida.

In the following description, the color-coding is in accordance with the Horticultural Color Chart of The Royal Horticultural Society, London, England (R.H.S. Colour Chart), and the Inter-Society color Council-Nation Bureau of Standard Color Name (I.S.C.C.-N.B.S. Color Name). A color designation based on The Japan Color Standard for Horticultural Plant (J.H.S. Color Chart) is also added for reference.

The `Rainbowcarpet rose` used as female parent in the obtaining of this new variety `SUNMAREF TP-SP`, is bred by the Takii Seed Corp., Japan and is commercially available. Such parent was registered on Jul. 15, 1989 as No. 1953 under the Seed and Seedling Law of Japan. The `Rainbowcarpet` series includes `Rainbowcarpet bright purple`, `Rainbowcarpet white` and the like. The main botanical characteristics of `Rainbow-carpet rose` are as follow.

Outward curvature of petal.--Slightly curved.

Diameter.--Approximately 1.0-1.5 cm.

Height.--Approximately 15-20 m m.

Color.--Strong purplish pink (R.H.S. 61D, JHS 9505) on the upper surface, and more purple on the under surface (R.H.S. 75A, JHS 8904). The throat coloration is pale purplish pink (R.H.S. 75, D, J H S 8902). The eye coloration is purplish white (R.H.S. 76D, JHS 8901).

Color intensity.--Absent.

Overlapping of petals.--Opened.

Spike.--Approximately 30-40 m m in length; and approximately 30-50 m m in diameter.

Calyx.--Approximately 0.5-1.0 cm in length.

Anthocyanin pigmentation of calyx limb.--Present.

Peduncle.--1 mm in thickness; and 4.0-5.0 cm in length.

Number of flowers.--Numerous (Approximately 10-14)

Reproductive organs.--pistil and 5 stamens.

Flower fragrance.--Absent.

Flowering duration.--Long.

Physiological and ecological characteristics: High resistance to diseases and pests, particularly powdery mildew. High tolerance to heat, cold, rain and drought exhibited. When provided with sufficient nutrition, the new variety of the present invention has been found to overwinter well when encountering temperatures as low as approximately - 5° C. However, the plant has been harmed when the temperatures encounted are as low as approximately -° C.

This new variety of Verbena plant is most suitable for growing as flower bedding and as a pot plant in planters, and is further is particulary well suited for growing as a ground cover. Upon self-pollination viable seed forms on the plant of the new variety of the present invention. However, such seed does not form plants identical to the new variety since the new variety is a F1 hybrid.

Pinching of the blossoms is not necessary to ensure continued blooming. It is found that such pinching will increase the number of blooms that are formed.

When the new variety of the present invention is compared to the `Sunmaref TP-L` variety (U.S. Plant Pat. No. 9,121), it is found that the upper petal surface is strong purplish pink (JHS 9505) for the new variety and vivid purple (JHS No. 8605) for the `Sunmaref TP-L` variety. Also, the flower eye coloration of the new variety is purplish white (JHS 8901) for the new variety and pale purple (JHS 8302) for the `Sunmaref TP-L` variety.

The plant of this new variety, `SUNMAREF TP-SP` is presently planted and maintained at the Plant Biotechnology Laboratory of SUNTORY Ltd., residing at 863-1 Aza-Iketani, Oomori-cho, Youkaiti-shi, Shiga-gun, Japan.
