USPP16511P3 - Osteospermum plant named ‘Oste Deeppur’ - Google Patents

Abstract

An Osteospermum cultivar particularly distinguished by purple colored flowers, dark green foliage and vigorous growth is described.

Description

Genus and species: Osteospermum ecklonis.

Variety denomination: ‘Oste Deeppur’.

BACKGROUND OF THE NEW PLANT

The variety ‘Oste Deeppur’ originated from a cross made in October, 2000. The female parent is a violet proprietary line OX-51 (unpatented). The male parent is ‘Denebola’, (patent status unknown) which is a commercial variety. Seed from this cross was sown in June 2001. In October 2001, single-plant selections were made for vegetative propagation using plant habit and flower color as selection criteria. One selection became the new variety ‘Oste Deeppur’.

‘Oste Deeppur’ is a product of a planned breeding program intended to create new Osteospermum cultivars with purple colored flowers, dark green foliage, and vigorous growth.

The new cultivar was created in 2000 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 ½ 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 propagation, and this novelty is firmly fixed.

DESCRIPTION OF PHOTOGRAPH

This new Osteospermum plant is illustrated by the accompanying photograph which shows blooms, buds, and foliage of the plant in full color, the colors shown being as true as can be reasonably obtained by conventional photographic procedures. Photos were taken from plants grown in The Netherlands in the late winter/spring in a greenhouse. Plants are 4½ months old, had one terminal pinch at 3 weeks old, and are grown in a 4 inch pot with 3 treatments of cyocel.

The photograph shows the mature plant with an inset photo of a close-up of the inflorescence.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Oste Deeppur’. The data, which defines these characteristics, were collected from asexual reproductions carried out in Gilroy, Calif. The plant history was taken on 5½ month old plants grown in six inch pots in the early summer season, in a LEXAN covered greenhouse under natural light and color readings were taken in the greenhouse under natural lights. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) 2001. Texture description details were observed under a dissecting microscope according to The New Royal Horticultural Society Dictionary of Gardening (1992).
