Osteospermum plant named ‘Sunny Felix’

Abstract

A new distinct cultivar of Osteospermum plant named ‘Sunny Felix’, characterized by its white ray florets with a small, but distinct violet-blue spot, violet-blue to gray-purple disc florets, dark green foliage, long ray florets measuring about 37 mm in length, and more leaves and shorter petioles than the typical Osteospermum variety.

Description

Botanical designation: Osteospermum ecklonis (DC) T. Norl.

Variety denomination: ‘Sunny Felix’.

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 variety denomination ‘Sunny Felix’.

The new Osteospermum is a product of a planned breeding program conducted by the inventor, Bjarne Larsen, in Stige, Odense, Denmark. The objective of the breeding program is to develop a new Osteospermum variety with inverted conical, compact, and upright plant habit, interesting inflorescence color, and good keeping quality.

The new Osteospermum originated from a planned crossing of two selected parent plants made by the inventor in 2002 in Stige, Odense, Denmark. The female or seed parent is an Osteospermum ecklonis (DC) T. Norl. cultivar designated ‘2.298.98’ (unpatented). The male or pollen parent is an Osteospermum ecklonis (DC) T. Norl. cultivar designated ‘9913’ (unpatented). The new Osteospermum cultivar ‘Sunny Felix’ was selected by the inventor as a single flowering plant within the progeny of the above crossing in 2003 in a controlled environment in Stige, Odense, Denmark.

Asexual reproduction of the new Osteospermum cultivar by apical stem cutting was first performed in February of 2003 in Stige, Odense, 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.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunny Felix’. These characteristics in combination distinguish ‘Sunny Felix’ as a new and distinct cultivar:

• • 1. White ray florets with a small, but distinct violet-blue spot;
  • 2. Violet-blue to gray-purple disc florets;
  • 3. Dark green foliage;
  • 4. Long ray florets, measuring about 37 mm in length; and
  • 5. More leaves and shorter petioles than a typical Osteospermum variety.

Plants of the parental cultivars, ‘2.298.98’ (unpatented) and ‘9913’ (unpatented) are not longer unavailable to provide a botanical comparison to plants of the new cultivar ‘Sunny Felix’.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to the new Osteospermum cultivar ‘Sunny Felix’ is the Osteospermum cultivar ‘Sunny Cecil’, (patented, U.S. Plant Pat. No. 15,273). In side-by-side comparisons conducted in Stige, Denmark, plants of ‘Sunny Felix’ differed from plants of ‘Sunny Cecil’ in the characteristics described in Table 1:

DETAILED BOTANICAL DESCRIPTION

The new Osteospermum cultivar ‘Sunny Felix’ 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 daylength, without any change in the genotype of the plant.

The aforementioned photographs, together with the following observations, measurements and values describe plants of the new Osteospermum cultivar ‘Sunny Felix’ as grown in a greenhouse in Stige, Odense, Denmark, under conditions which closely approximate those generally used in commercial practice and garden use Vegetative propagation with apical tip cuttings (4-5 leaves) took place in a greenhouse with propagation tents for 3 weeks with the day and night temperature averaging about 20° C. The temperature was then lowered to the day and night temperature averaging about 14° C. The plants were subirrigated with a nutrient solution of 2-3 mS when needed and given supplementary irradiation with SON T lamps having an installed energy level of 400 Wm².

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), 4^th edition 2000, except where general colors of ordinary significance are used. The photographs and descriptions were taken during the spring season when outdoor day temperatures ranged from 7° C. to 15° C. and outdoor night temperatures ranged from 0° C. to 7° C. The age of the plants described is 20 weeks.
