Description

Description

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

Variety denomination: ‘DAOSENOGTYVE’.

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 ‘DAOSENOGTYVE’.

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 light pink Osteospermum variety designated 5645A (not patented). The male or pollen parent is a dark purple colored Osteospermum cultivar named ‘Sunny Mary’ (U.S. Plant Pat. No. 16,389 P13).

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 ‘DAOSENOGTYVE’, which in combination distinguish this Osteospermum as a new and distinct cultivar:

- 1. Vigorous cultivar, with globular upright to spreading shape;
- 2. Stiff and strong lateral stems and thick leaves. Color of mature leaves is RHS 139A (upper side) RHS 137B (underside);
- 3. Ray florets with a unique color combination, RHS Red-purple 72A with stripes of RHS Purple N79C or darker, RHS White N155A edges at the upper side, and stripes in various violet colors from RHS Violet 85A to RHS Violet 84A on the underside; and
- 4. Disk florets that appear RHS Violet 83A or darker.

Plants of the new Osteospermum ‘DAOSENOGTYVE’ differ from plants of the parents, 5645A (unpatented) and ‘Sunny Mary’ (U.S. Plant Pat. No. 16,389 P13) in the traits described in Table 1.

DETAILED BOTANICAL DESCRIPTION

The new Osteospermum ‘DAOSENOGTYVE’ 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 ‘DAOSENOGTYVE’ 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 (mS/m) levels in the soil were 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 ‘DAOSENOGTYVE’ plants described is 12 weeks from potting.
