Abstract

A new distinct cultivar of Osteospermum plant named ‘Shiela’, characterized by short, dense and bushy plant form with inverse pyramidal shape; more upright stems and differently shaped leaves; more large, upright inflorescences per plant consisting of ray florets that are primarily orange-red in color with red-purple color at base, and dark red-purple disc florets; and vigorous growth habit.

Description

Botanical designation: Osteospermum ecklonis (DC) T. Norl.
Cultivar denomination: ‘Shiela’.
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 denomination ‘Shiela’.
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 cultivar with upright, compact plant habit, interesting inflorescence color, good branching performance, low growth retardant requirements and low temperature tolerance.
The new Osteospermum originated from a planned crossing made by the Inventor in 2003 in Stige, Odense, Denmark. The female or seed parent is ‘Sunny Serena’, (patented, U.S. Plant Pat. No. 15,693). The male or pollen parent is Osteospermum ecklonis cultivar designated ‘30.013.01’ (unpatented). The new Osteospermum cultivar ‘Shiela’ was selected by the Inventor as a 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 cuttings was first performed in June 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 unique characteristics of ‘Shiela’. These characteristics in combination distinguish ‘Shiela’ as a new and distinct cultivar:
    • 1. short, dense and bushy plant form with inverse pyramidal shape;
    • 2. more upright stems and differently shaped leaves;
    • 3. more large, upright inflorescences per plant consisting of ray florets that are primarily orange-red in color with red-purple color at base, and dark red-purple disc florets; and
    • 4. vigorous growth habit.
Plants of the new cultivar ‘Shiela’ differ from plants of the parental cultivar, ‘Sunny Serena’ (patented, U.S. Plant Pat. No. 15,693) in the characteristics described in Table 1.

 DETAILED BOTANICAL DESCRIPTION
The new Osteospermum cultivar ‘Shiela’ 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 plants of the new Osteospermum cultivar ‘Shiela’ as grown in a greenhouse and outside 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 of The Royal Horticultural Society Colour Chart (R.H.S.), 4th 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 after planting.
