Abstract

A new distinct cultivar of Osteospermum plant named ‘Sunny Henry’, characterized by white ray floret color 158D with slight green-yellow tinge, RHS 1B, to pure white, RHS 155D; dense and bushy plant form, mainly due to upright stems; vigorous growth habit; less need for chemical growth retardation; and high number of inflorescences per plant.

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.
