Abstract

A new petunia plant particularly distinguished by medium to large, light bluish-violet flowers with dark throats and distinct dark veins, medium to deep-green foliage with wide leaves, a medium, round, bushy, moderately tight plant habit with moderately vigorous growth, an initially upright and spreading to later prostrate or trailing plant habit with an early and continuous flowering response, is disclosed.

Description

Genus and species: Petunia sp.
Variety denomination: ‘Jam Bluintwo’.
BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct cultivar of petunia, botanically known as Petunia sp., and hereinafter referred to by the cultivar name ‘Jam Bluintwo’. The new cultivar originated from a hybridization made in February 2001 in Gilroy, Calif. The female parent was ‘643-1’, a proprietary purple-flowered petunia plant (unpatented) with strong veins, while the male parent was ‘Revolution Bluevein’, a commercial light bluish-violet-flowered petunia plant (U.S. Plant Pat. No. 9,322) with distinct dark veins and a dark throat.
The new cultivar was created in 2001 in Gilroy, Calif. and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Gilroy, Calif. and Andijk, The Netherlands over a three-year period. The plant has also been trialed at Gilroy, Calif. and Andijk, The Netherlands. 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 Canada on Mar. 29, 2005, in Switzerland on Sep. 16, 2005 and with the European Union on Sep. 28, 2005.
SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Gilroy, Calif. and Hillscheid, Germany.
    • 1. Medium to large light bluish-violet flowers with dark throats and distinct dark veins;
    • 2. Medium to deep-green foliage with wide leaves;
    • 3. A medium sized, rounded, bushy and moderately tight plant habit;
    • 4. Moderately vigorous growth;
    • 5. An initially upright and spreading to later prostrate or trailing plant habit; and
    • 6. An early and continuous flowering response.
DESCRIPTION OF PHOTOGRAPHS
This new petunia plant is illustrated by the accompanying photographs which show 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 3-month-old plants grown in a greenhouse in Hillscheid, Germany.
FIG. 1 shows the overall plant habit, including blooms, buds, mature foliage, and plant habit.
FIG. 2 shows a close-up of the mature inflorescences
DESCRIPTION OF THE NEW CULTIVAR
The following detailed description sets forth the distinctive characteristics of ‘Jam Bluintwo’. The data which define these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. The plant history was taken on 5 to 6 -week old plants which were planted as rooted cuttings in 12-cm pots in early July 2005 and grown in a greenhouse. The plants were pinched once. Observations were made when the plants were in full flower in August 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).
