USPP18051P2 - Petunia plant named ‘Jam Plumein’ - Google Patents

Abstract

A new petunia plant particularly distinguished by large, purple to purple-pink flowers with strong dark veins, medium-green foliage with elliptical leaves, a medium, round, bushy, moderately tight plant habit with moderately vigorous growth, an initially low spreading to later decumbent or trailing plant habit with an early to medium and continuous flowering response, is disclosed.

Description

Genus and species:

Variety denomination: ‘Jam Plumein’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of petunia, botanically known as a Petunia sp., and hereinafter referred to by the cultivar name ‘Jam Plumein’. The new cultivar originated from a hybridization made in February 2003 in Gilroy, Calif. The female parent was ‘Jam Bluintwo’, a blue-flowered proprietary petunia plant (U.S. patent application Ser. No. 11/369,365) with dark veins, while the male parent was ‘Revolution Pinkvein’, a pink-flowered commercial petunia plant (U.S. Plant Pat. No. 9,341) with dark veins.

The new cultivar was created in 2003 in Gilroy, Calif. and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Gilroy, Calif. and Andijk, The Netherlands over a two-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 Jul. 19, 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. Large purple to purple-pink flowers with strong, dark violet veins;
  • 2. Medium-green foliage with elliptical leaves;
  • 3. A medium sized, rounded, bushy and relatively tight plant habit;
  • 4. Moderately vigorous growth;
  • 5. An initially low spreading to later decumbent or trailing plant habit; and
  • 6. An early to mid-season and continuous flowering response.

DESCRIPTION OF PHOTOGRAPH

This new petunia plant is illustrated by the accompanying photograph which shows 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 photograph is of a 3-month-old plant grown in a greenhouse in Hillscheid, Germany.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘Jam Plumein’. 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).
