Description

Genus and species: Petunia hybrida Vilm.

Variety denomination: ‘Keipunes’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of petunia, botanically known as Petunia hybrida Vilm., and hereinafter referred to by the cultivar name ‘Keipunes’. The new cultivar originated from a hybridization made in October 2000 in Katori, Chiba, Japan. The female parent was a proprietary unnamed petunia plant (unpatented), while the male parent was a different proprietary unnamed petunia plant (unpatented).

The new cultivar was created in 2000 in Katori, Chiba, Japan and has been asexually reproduced repeatedly by vegetative cuttings in Katori, Chiba, Japan. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this cultivar were applied for in Switzerland on Jul. 20, 2005, in Norway on Jan. 12, 2006 and with the European Union on Feb. 20, 2006.

SUMMARY OF THE INVENTION

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

    • A) Abundant, small-size, vivid red-purple flowers;
    • B) Abundant branching with a great profusion of blooms;
    • C) Vigorous, decumbent growth habit;
    • D) Excellent tolerance to rain; and
    • E) Whole plant remains in bloom for a considerable period of time.

DESCRIPTION OF PHOTOGRAPHS

This new petunia plant is illustrated by the accompanying photographs which show blooms and foliage of the plant in full color, the colors shown being as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 2-month-old plant grown in a greenhouse in Katori, Chiba, Japan.

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

FIG. 2 shows the mature flower.

 DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘Keipunes’. The data which define these characteristics were collected from asexual reproductions carried out in Katori, Chiba, Japan. The plant history was taken on 2-month old plants which were planted as rooted cuttings in 12-cm pots in 2005 and grown in a greenhouse between 18° C. and 25° C. The plants were pinched once in September 2005. Observations were made when the plants were in full flower in October 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

‘Keipunes’ differs from the female parent, an unnamed proprietary petunia plant (unpatented), by having a decumbent plant habit, while the female parent has a spreading plant habit. Additionally, ‘Keipunes’ has a shorter plant height and a smaller flower diameter than the female parent.

‘Keipunes’ differs from the male parent, an unnamed proprietary petunia plant (unpatented), by having a taller plant height, a larger flower diameter, and a larger plant diameter, than the male parent.

‘Keipunes’ is similar to the commercial variety ‘Revolution Brilliantpink’ (U.S. Plant Pat. No. 6,914) however, there are differences as listed in Table 1 below:
