Osteospermum plant named ‘Sunny Philip’

Abstract

A new distinct cultivar of Osteospermum plant named ‘Sunny Philip’, characterized by its large upright purple inflorescences; spatulate ray florets with colors: (upper surfaces) RHS 155A, white to RHS 87B, violet, at base and (underside) RHS 86C, violet to RHS 85D, violet at base; compact and bushy plant form, mainly due to upright stems; moderately vigorous growth habit, but less need for chemical growth retardation; and high number of large inflorescences per plant.

Description

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

Variety denomination: ‘Sunny Philip’.

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 Philip’.

The new Osteospermum is a product of a planned breeding program conducted by the Inventor, Bjarne Larsen, in Stige, Denmark. The new Osteospermum originated from a controlled cross breeding made in May 2000 by the Inventor between Osteospermum ecklonis (DC) T. Norl. designated ‘3.122.983’ (unpatented) and Osteospermum ecklonis (DC) T. Norl. designated ‘9913’ (unpatented). The Inventor selected the new Osteospermum cultivar from the progeny of the above crossing in 2003 on the basis of its inflorescence color, size, 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 ray florets.

Asexual reproduction of the new cultivar by terminal cuttings taken and propagated at 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.

SUMMARY OF THE INVENTION

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

• • 1. Large upright purple inflorescences;
  • 2. Spatulate ray florets with colors: (upper surfaces) RHS 155A, white to RHS 87B, violet, at base and (underside) RHS 86C, violet to RHS 85 D, violet at base.
  • 3. Compact and bushy plant form, mainly due to upright stems;
  • 4. Moderately vigorous growth habit, but less need for chemical growth retardation; and
  • 5. High number of large inflorescences per plant.

Plants of the cultivar ‘Sunny Philip’ can be compared to plants of the Osteospermum ecklonis (DC) T. Norl. Cultivar ‘Sunny Zara’ (unpatented). However, in side-by-side comparisons conducted by the Inventor in Stige Denmark, plants of the cultivar ‘Sunny Philip’ and the cultivar ‘Sunny Zara’ differ in the following characteristics:

• • 1. Plants of the new Osteospermum have striking color combinations of white/violet ray florets and violet-blue disk with orange pollen.
  • 2. Plants of the new Osteospermum have darker green leaves while plants of the cultivar ‘Sunny Zara’ have yellow-green-colored leaves.
  • 3. Plants of the new Osteospermum are shorter and more compact than the plants of the cultivar ‘Sunny Zara’.
  • 4. Plants of the new Osteospermum have more inflorescences per plant than the plants of the cultivar ‘Sunny Zara’ as well as larger inflorescences.

Plants of the cultivar ‘Sunny Philip’ can be compared to plants of the parental cultivars ‘3.122.983’ and ‘9913’. Plants of the cultivar ‘Sunny Philip’ differ from plants of the parental cultivars, ‘3.122.983’ and ‘9913’, primarily in inflorescence color.

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