Abstract

A new calibrachoa plant particularly distinguished by deep-violet flowers, abundant branching with a great profusion of blooms, continuously flowers from spring to late fall, excellent tolerance to rain and high temperatures, and a vigorous, mounding plant habit is disclosed.

Description

Genus and species: Calibrachoa sp.

Variety denomination: ‘Sunbelsafu’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of calibrachoa, botanically known as Calibrachoa sp., and hereinafter referred to by the cultivar name ‘Sunbelsafu’. The new cultivar originated from a hybridization made in April 2002 in Higashiomi, Shiga, Japan. The female parent was the proprietary calibrachoa plant ‘V14’ (unpatented), while the male parent was the proprietary calibrachoa plant ‘P30’ (unpatented).

The new cultivar was created in 2002 in Higashiomi, Shiga, Japan and has been asexually reproduced repeatedly by vegetative cuttings in Higashiomi, Shiga, Japan. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Higashiomi, Shiga, Japan.

- 1. Deep-violet flowers;
- 2. Abundant branching with a great profusion of blooms;
- 3. Vigorous and mounding plant habit;
- 4. Continuously flowers from spring to late fall; and
- 5. Excellent tolerance to rain and high temperatures.

DESCRIPTION OF PHOTOGRAPHS

This new calibrachoa plant is illustrated by the accompanying photographs which show the overall plant habit including blooms, buds and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 4-month-old plant grown outdoors in Higashiomi, Shiga, Japan.

FIG. 1 shows the overall plant habit, including blooms, buds and foliage.

FIG. 2 shows mature flowers.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘Sunbelsafu’. The data which define these characteristics were collected from asexual reproductions carried out in Higashiomi, Shiga, Japan. The plant history was taken on 4-month old plants which were planted as rooted cuttings in 15-cm pots in a spring trial setting in 2005 and grown outdoors in temperatures ranging between 13° C. and 23° C. The plants were pinched once in April 2005. Observations were made when the plants were in full flower in May 2005. Color readings were taken under natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘Sunbelsafu’ differs from the female parent ‘V14’ (unpatented), by having deep violet flowers and a mounding growth habit, while ‘V14’ has violet flowers and a spreading growth habit.

‘Sunbelsafu’ differs from the male parent ‘P30’ (unpatented), by having deep violet flowers and shallow corolla lobing, while ‘P30’ has purple flowers and deeper corolla lobing. Additionally, ‘Sunbelsafu’ has a larger flower diameter than ‘P30’.

‘Sunbelsafu’ is similar to the commercial variety ‘Sunbelchipi’ (U.S. Plant Pat. No. 10,355) however, there are differences as listed in Table 1 below:
