Osteospermum plant named ‘Sunny Davina’

Abstract

A new and distinct cultivar of osteospermum plant named Sunny Davina, particularly characterized by its ray-floret color, in which the upper surface of mature ray florets having alternate stripes of a darker and a lighter purple, upright growth habit, elliptic ray florets in one or two complete whorls, and by its nonvariegated leaves.

Description

The present invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as Osteospermum ecklonis, and referred to by the varietal denomination ‘Sunny Davina’.

The new cultivar is the product of a planned breeding program carried out by the inventor is Odense, Denmark. The objective of the breeding program was to create new osteospermum cultivars with distinctly new inflorescence colors.

The new cultivar originated from a cross made by the inventor in Odense, Denmark, in May 2002. The female or seed parent was the cultivar ‘Sunny Serena’, disclosed in U.S. Plant Pat. No. 15,693, and primarily characterized by its compact, upright, mounded-plant habit, its dense and bushy growth habit, its freely flowering habit, and its pale yellow ray florets and contrasting grey disc florets. The male or pollen parent was an unnamed and unpatented proprietary seedling identified by the code number 30.013.01. The characteristics of the male parent are not presently available.

The first act of asexual reproduction of the new cultivar was accomplished when vegetative cuttings were made from the selection in April 2004 in a controlled environment in Odense, Denmark, by or under the supervision of the inventor.

The new cultivar has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment, such as temperature, light intensity, and day length without, however, any variance in genotype.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and have been determined to be basic characteristics of the new cultivar, which, in combination, distinguish the new cultivar as being new and distinct:

• • 1. The new cultivar has an upright growing habit, and possesses many of the growth characteristics of the female parent, ‘Sunny Serena’.
  • 2. Nonvariegated leaves.
  • 3. Elliptic ray florets formed in one or two complete ray floret whorls.
  • 4. The ray-floret color is unique, with the upper surfaces of the ray florets having alternate stripes of a darker purple (78A) and a lighter purple (78B), creating a very interesting effect.

Of the many commercial cultivars known to the present inventor(s), the most similar cultivar in comparison to the new cultivar is the female parent, ‘Sunny Serena’. The primary distinction is in ray floret color, with the color of the upper side of the ray florets of ‘Sunny Serena’ being a solid, pale orange (RHS 19D).

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The photograph at the bottom of the sheet shows a front perspective view of typical flowering plants (three) of the new cultivar. The photograph at the top of the sheet is a view showing in more detail the inflorescences of the new cultivar, particularly the novel striping on the upper surface of the ray florets.

The colors in the photographs are as true as is reasonably possible with colored reproductions of this type. If any difference exist between the photographic color and the color values described below, the values in the detailed description are accurate.
