Description

Description

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

Variety denomination: ‘DAOSTREOGTYVE’.

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 hereinafter referred to by the cultivar name ‘DAOSTREOGTYVE’.

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 is originated from a mutation found in ‘DAOSSEKSTEN’ (U.S. Plant Patent Application Publication No. 20120255082) selected by the inventor in 2009, in Stige, Denmark.

Asexual reproduction of the new Osteospermum cultivar by terminal cuttings was first performed in November, 2009 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 ‘DAOSTREOGTYVE’, 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 RHS Red 39A when opening and developing into RHS Red 53B when fully open on upper side; and
- 4. Disc florets that appear grayed-orange (RHS 166A).

Plants of the new Osteospermum ‘DAOSTREOGTYVE’ differ from ‘DAOSSEKSTEN’ (U.S. Plant Patent Application Publication No. 20120255082), from which it is mutated, in the traits described in Table 1.

DETAILED BOTANICAL DESCRIPTION

The new Osteospermum ‘DAOSTREOGTYVE’ 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 ‘DAOSTREOGTYVE’ 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 were 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 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 January daylight conditions at approximately 11:00-13:00 in Stige, Denmark. The age of the ‘DAOSTREOGTYVE’ plants described is 12 weeks from potting.
