Description

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

Variety denomination: ‘DAOSSEKSTEN’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as Osteospermum ecklonis (DC) T. Norl., commonly known as Cape Daisy and and hereinafter referred to by the cultivar name ‘DAOSSEKSTEN’.

The new Osteospermum cultivar is a product of a planned breeding program conducted by the inventor, Rune Nielsen, in Stige, Denmark. The objective of the breeding program is to develop a new Osteospermum cultivar with good garden performance, well branching growth, continuous flowering and an attractive inflorescence color.

The new Ostospermum cultivar originated from a cross made in a controlled breeding program by the inventor in 2007, in Stige, Denmark. The female or seed parent is a yellow colored Osteospermum cultivar Sunny® ‘Shiela’ (patented, U.S. Plant Pat. No. 18,066). The male or pollen parent is an orange colored Osteospermum ‘DAOSTOLV’ (Plant Breeder's Right, CPVO No. 2008/0604).

Asexual reproduction of the new Osteospermum cultivar by terminal cuttings was first performed in November, 2008 in Stige, Denmark, and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘DAOSSEKSTEN’, which in combination distinguish this Osteospermum as a new and distinct cultivar:

    • 1. Compact cultivar, with globular upright to spreading shape;
    • 2. Very well branching (8-14 per plant) with stiff and strong lateral stems and small thick leaves. Color of leaves Green RHS 139A (upper side) Green RHS 137B (underside);
    • 3. Ray florets with Orange color (RHS 26A) on upper side; and
    • 4. Disc florets that appear grayed brown (RHS N199A).

Plants of the new Osteospermum ‘DAOSSEKSTEN’ differ from plants of the parents, Sunny® ‘Shiela’ (U.S. Plant Pat. No. 18,066) and ‘DAOSTOLV’ (CPVO No. 2008/0604) in the traits described in Table 1.

 DETAILED BOTANICAL DESCRIPTION

The new Osteospermum ‘DAOSSEKSTEN’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant.

The aforementioned photographs, together with the following observations, measurements and values describe the new Osteospermum ‘DAOSSEKSTEN’ as grown in a glasshouse, equipped with heat, assimilation light and ebb/flood watering system in Odense, Denmark, under conditions which closely approximate those generally used in commercial practice. The plants was grown in 14° C., with a venting temperature on 16° C. Assimilation light was given when natural daylight was below 3000 lux and the day length was extended to 16 hours. The EC levels in the soil, was kept at about 2.5-3.5 and pH around 6.0 during the production. Plant growth was regulated 3 times during the production period, using 3‰ Cycocel (chlormequat-chloride) as a drench (80-100 ml/pot).

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), Colour Chart 2001 edition, Color values were taken under March daylight conditions at approximately 10:00-14:00 in Stige, Denmark. The age of the ‘DAOSSEKSTEN’ plants described is 12 weeks from potting.
