Description

Latin name of the genus and species of the plant claimed: Osteospermum ecklonis.

Varietal denomination: ‘OSTZ0003’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Osteospermum, botanically known as Osteospermum ecklonis, and hereinafter referred to by the variety name ‘OSTZ0003’.

‘OSTZ0003’ is a product of a planned breeding program. The new cultivar ‘OSTZ0003’ has yellow colored inflorescences held nicely above the foliage, medium-green foliage, with early flowering and an excellent branched and compact bushy habit.

‘OSTZ0003’ originates from an open-pollinated hybridization made in August 2007 in greenhouse in Andijk, The Netherlands. The female parent was an unpatented, proprietary plant identified as ‘98-10’ with bronze-yellow color, with a later flowering habit and fewer branches when compared to ‘OSTZ0003’.

The male parent of ‘OSTZ0003’ is unknown. The resultant seed was sown in March 2008. ‘OSTZ0003’ was selected as one flowering plant within the progeny of the stated cross in August 2008 in a greenhouse in Andijk, The Netherlands.

The first act of asexual reproduction of ‘OSTZ0003’ was accomplished when vegetative cuttings were propagated from the initial selection in August 2008 in a greenhouse in Andijk, The Netherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in August, 2008 in Andijk, The Netherlands, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘OSTZ0003’ are firmly fixed and are retained through successive generations of asexual reproduction.

Plant Breeder's Rights for this cultivar were applied for in Canada on Nov. 1, 2011 (11-7413) and at the Community Plant Variety Office on Jul. 20, 2012 (2012/1620). ‘OSTZ0003’ has not been made publicly available more than one year prior to the filing of this application.

‘OSTZ0003’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Osteospermum as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘OSTZ0003’ with colors being as true as possible with an illustration of this type. The photographic drawing shows in FIG. 1 a flowering plant of the new variety and in FIG. 2 a close-up of an inflorescence.

 DETAILED BOTANICAL DESCRIPTION

The plant measurements and descriptions were taken in Enkhuizen, The Netherlands, in early September 2012 using plants that were growing in a field trial and were about 27 weeks of age.

The aforementioned photograph for FIG. 1 was taken in Enkhuizen, The Netherlands in April 2011. The plants were growing in 10 cm pots in a greenhouse trial and were about 13 weeks of age. The aforementioned photograph for FIG. 2 was taken in Gilroy, Calif. in April 2011. The plants used were growing in 4.5 inch pots in a greenhouse trial and were about 13-14 weeks of age.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
