USPP17615P2 - Calibrachoa plant named ‘Sunbelkuriho’ - Google Patents

Abstract

A new and distinct cultivar of Calibrachoa plant named ‘Sunbelkuriho’, characterized by its outwardly spreading, trailing and decumbent plant habit; vigorous growth habit; freely branching habit; freely flowering habit; long flowering period; white-colored flowers; and good weather tolerance.

Description

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘Sunbelkuriho’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa sp., and hereinafter referred to by the cultivar name ‘Sunbelkuriho’.

The new Calibrachoa is a naturally-occurring branch mutation of the Calibrachoa sp. cultivar Sunbelbura, disclosed in U.S. Plant Pat. No. 14,405. The new Calibrachoa was discovered and selected by the Inventors in a controlled environment in Higashiomi, Shiga, Japan in September, 2002.

Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Higashiomi, Shiga, Japan since April, 2003, has shown that the unique features of this new Calibrachoa are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Sunbelkuriho have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity and daylength without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunbelkuriho’. These characteristics in combination distinguish ‘Sunbelkuriho’ as a new and distinct cultivar of Calibrachoa:

• • 1. Outwardly spreading, trailing and decumbent plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Long flowering period.
  • 6. White-colored flowers.
  • 7. Good weather tolerance; tolerant to rain and low and high temperatures.

Plants of the new Calibrachoa differ primarily from plants of the parent, the cultivar Sunbelbura, in flower color as plants of the cultivar Sunbelbura have red purple-colored flowers.

Plants of the new Calibrachoa can be compared to plants of the cultivar Sunbelkuho, disclosed in U.S. Plant Pat. No. 10,278. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Calibrachoa were broader and had smaller leaves than plants of the cultivar Sunbelkuho. In addition, plants of the new Calibrachoa had larger flowers than plants of the cultivar Sunbelkuho.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Calibrachoa.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sunbelkuriho’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of typical flowers and leaves of ‘Sunbelkuriho’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. Plants grown in 25-cm containers for about seven months were used for the aforementioned photographs and following description. Plants were grown under conditions which closely approximate commercial production conditions during the summer in Higashiomi, Shiga, Japan in an outdoor nursery. During the production period, day temperatures were about 25° C. and night temperatures were about 15° C. Plants were pinched one time in the spring.
