Abstract

A distinct cultivar of Osteospermum plant named ‘Pemba’, characterized by its upright plant habit; numerous inflorescences per plant; and spoon-shaped dark pink ray florets with blue disc florets.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as Osteospermum ecklonis and referred to by the cultivar name Pemba.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Aabyhoj, Denmark. The objective of the breeding program was to create new Osteospermum cultivars with interesting ray floret colors.
The new cultivar originated from a cross made by the Inventor in 1995 of a proprietary selection of Osteospermum ecklonis identified as 9511 as the female, or seed, parent and a proprietary selection of Osteospermum ecklonis identified as 9524 as the male, or pollen, parent. The new Osteospermum was selected by the Inventor as a flowering plant within the progeny of this cross in a controlled environment in Aabyhoj, Denmark, in 1996.
Plants of the new cultivar are different from plants of the female parent, the selection 9511, in ray floret color.
Plants of the new Osteospermum are different from plants of the male parent, the selection 9524, in plant size and coloration of lower surface of ray florets.
Asexual propagation of the new cultivar by terminal cuttings at Aabyhoj, has shown that the unique features of this new Osteospermum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Pemba’. These characteristics in combination distinguish ‘Pemba’ as a new and distinct cultivar:
1. Upright plant habit.
2. Numerous inflorescences per plant.
3. Spoon-shaped dark pink ray florets with blue disc florets.
The new cultivar can be compared to the Osteospermum cultivar Sunny Sonja, disclosed in U.S. Plant Pat. No. 10,341. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new cultivar are taller; more freely branching; have more numerous but smaller leaves; are more floriferous; and have longer peduncles than plants of the cultivar Sunny Sonja.
The cultivar Pemba has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Pemba’.
The photograph at the bottom of the sheet is a close-up view of typical inflorescences and young and mature leaves of ‘Pemba’ (code number 9607 in the photograph) and ‘Sunny Sonja’ (Sonja in the photograph). Foliage and floret colors in the photographs may appear different from the actual colors due to light reflectance.
DETAILED BOTANICAL DESCRIPTION
The following observations, measurements and values describe one-gallon containers of the new cultivar grown in Encinitas, Calif., under outdoor, full-sun conditions with day temperatures ranging from 20 to 27° C. and night temperatures ranging from 6 to 14° C. Plants were pinched (terminal apex removed) one time about two weeks after planting rooted cuttings. Plants used for this description were grown for about 12 to 14 weeks after planting rooted cuttings.
Color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
