Description

Genus and species of the plant claimed: Osteospermum ecklonis (DC) T Norl.

Variety denomination: ‘Sunny Henry’.

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 by the name Cape Daisy, and hereinafter referred to by the name ‘Sunny Henry’.

The new Osteospermum is a product of a planned breeding program conducted by the Inventor, Bjarne N. Larsen, in Stige, Denmark. The new Osteospermum originated from a cross made in 2000 by the Inventor between Osteospermum ecklonis (DC) T. Norl. designated ‘1.154.93’ (unpatented) and Osteospermum ecklonis (DC) T. Norl. variety name ‘Sunny Alex’ (unpatented). The Inventor selected the new Osteospermum cultivar from the progeny of the above crossing in 2002 on the basis of its inflorescence color and compact, freely branching habit. Plants of the new Osteospermum are upright, compact and have a unique color combination of upper and underside of the rayflorets.

Asexual reproduction of the new cultivar by terminal vegetative cuttings taken and propagated during trial production batches in Stige, Denmark, has shown that the unique features of this new Osteospermum are stable and reproduced true to type in many successive generations.

BRIEF SUMMARY OF THE INVENTION

Plants of the cultivar ‘Sunny Henry’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with the variations in environment such as temperature, light intensity, day length, and fertility level without, however, any variance in genotype.

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

    • 1. White ray floret color, RHS 158D, with slight green-yellow tinge, RHS 1B, to pure white, RHS 155D.
    • 2. Dense and bushy plant form, mainly due to more upright stems.
    • 3. Vigorous growth habit; less need for chemical growth retardation.
    • 4. High number of inflorescences per plant.

Plants of the cultivar ‘Sunny Henry’ can be compared to plants of the parental cultivar ‘1.154.93’. Plants of the cultivar ‘Sunny Henry’ differ from plants of the parental cultivar, ‘1.154.93’, primarily in inflorescence color.

Plants of ‘Sunny Henry’ differ from plants of the parental cultivar, ‘Sunny Alex’ in the following characteristics described in Table 1:

TABLE 1 Trait ‘Sunny Henry’ ‘Sunny Alex’ Plant height 15 cm 17 cm Width 18 cm 17 cm Inflorescence Color White Orange-yellow Foliage Single, obovate to Broadly lobed lanceolate

Plants of the cultivar ‘Sunny Henry’ can be compared to plants of the Osteospermum ecklonis (DC) T. Norl. cultivar ‘Sunny Gustav’ (U.S. Plant Pat. No. 10,670). In side-by-side comparisons conducted by the Inventor in Stige Denmark, plants of the cultivar ‘Sunny Henry’ and the cultivar ‘Sunny Gustav’ differ in the following characteristics:

    • 1. ‘Sunny Henry’ has striking white ray florets, RHS 155C, and white disk florets, RHS N155D, with orange pollen, while ‘Sunny Gustav’ has a white flower with blue eye.
    • 2. ‘Sunny Henry’ has yellow-green-colored leaves while plants of the cultivar ‘Sunny Gustav’ have darker green leaves.
    • 3. ‘Sunny Henry’ has shorter peduncles than plants of the cultivar ‘Sunny Gustav’.
    • 4. ‘Sunny Henry’ is shorter and more compact than the plants of the cultivar ‘Sunny Gustav’.
    • 5. ‘Sunny Henry’ has more and larger inflorescences per plant than the plants of the cultivar ‘Sunny Gustav’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs illustrate the overall appearance of the new Osteospermum cultivar ‘Sunny Henry’ showing the colors as true as is reasonably possible with colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the color of the new Osteospermum cultivar ‘Sunny Henry’.

The first photograph comprises a side perspective view of a typical flowering plant of ‘Sunny Henry’ as grown in an 11 cm pot.

The second photograph is a close-up of the young and older inflorescences of ‘Sunny Henry’.

The third photograph is a top view of a typical flowering plant of ‘Sunny Henry’.

The fourth photograph shows the inflorescences and leaves of ‘Sunny Henry’ (in the fourth photograph, ‘Sunny Henry’ is labelled by its breeder's reference no. ‘10.514.01’).

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 4th edition, where general terms of ordinary dictionary significance are used. Plants were grown under greenhouse conditions. The plants described were grown for about 20 weeks after cutting.

  • Plant description:
      • Form.—Perennial plant with upright, globular plant habit; composite flower heads; freely branching with lateral flowering branches forming at every node; dense and bushy.
