Description

Genus and species: Osteospermum ecklonis Norl.

Variety denomination: ‘Trad Purbilor’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Osteospermum, botanically known as Osteospermum ecklonis Norl., and hereinafter referred to by the cultivar name ‘Trad Purbilor’. The new cultivar originated from a hybridization made in June 1999. The female parent was the proprietary ‘OY-85-6’ (unpatented) Osteospermum plant, with light purple inflorescences, while the male parent was the proprietary ‘OY-81-2’ (unpatented) Osteospermum plant, with purple inflorescences. The seeds produced by the hybridization were sown in August 2003. A single plant selection was chosen for further evaluation and for asexual propagation in January 2004.

The new cultivar was created in 1999 in Andijk, The Netherlands, and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Andijk, The Netherlands, Gilroy, Calif. and Hillscheid, Germany over a 2 and a half year period. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this cultivar have been applied for in Canada on Mar. 21, 2006 and in Switzerland on Nov. 13, 2006.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of the new cultivar when grown under normal horticultural practices in Gilroy, Calif., Andijk, The Netherlands and Hillscheid, Germany.

    • 1. Purple and white inflorescences;
    • 2. An upright and medium-sized plant habit; and
    • 3. A freely branching and vigorous growth habit.

DESCRIPTION OF THE PHOTOGRAPHS

This new Osteospermum plant is illustrated by the accompanying photographs which show overall plant habit including inflorescences, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures.

FIG. 1 shows a close-up of a 12-week-old plant grown in a greenhouse in Hillscheid, Germany in May 2006.

FIG. 2 shows the overall plant habit, including blooms, buds, mature foliage, and the mature inflorescences of a 20-week old plant, grown in France in August 2006.

 DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Trad Purbilor’. The data which define these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. The plant history was taken on 12-week-old plants, grown in 4-inch pots in a greenhouse during the early spring. The plants had one plant growth regulator treatment and one terminal pinch early in the trial. Color readings were taken under natural light in the greenhouse in March. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001). Texture description data was viewed with a dissecting microscope.
