Abstract

A distinct cultivar of Osteospermum plant named ‘Dondo’, characterized by its upright and outwardly spreading plant habit; numerous inflorescences per plant; pink ray florets with blue disc florets; and tolerance to high temperatures.

Description

BACKGROUND OF THE INVENTION
The invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as Osteospermum ecklonis and referred to by the cultivar name Dondo.
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 proprietary selection of Osteospermum ecklonis identified as 949343 as the female, or seed, parent and a proprietary selection of Osteospermum ecklonis identified as 949322 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 949343, in inflorescence size and quantity of ray florets.
Plants of the new Osteospermum are different from plants of the male parent, the selection 949322, in plant habit inflorescence size and quantity of ray florets.
Asexual propagation of the new cultivar by terminal cutting 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 ‘Dondo’. These characteristics in combination distinguish ‘Dondo’ as a new and distinct cultivar:
1. Upright and outwardly spreading plant habit.
2. Numerous inflorescences per plant.
3. Pink ray florets with blue disc florets.
4. Tolerance to high temperatures.
The new cultivar can be compared to the Osteospermum cultivar Cape Daisy Congo, disclosed in U.S. Plant Pat. No. 10,342. In side-by-side comparisons conducted in Aabyhoj, Denmark, and Encinitas, Calif., plants of the new cultivar are smaller and less vigorous; are less freely branching; have smaller inflorescences; have darker red purple ray florets that resist fading better; and are more high temperature tolerant than plants of the cultivar Cape Daisy Congo.
The cultivar Dondo 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. Colors in the photographs may differ slighty from color values cited in the detailed botanical description which more accurately describes the actual colors of the new Osteospermum.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Dondo’.
The photograph at the bottom of the sheet is a close-up view of typical inflorescences and young and mature leaves of ‘Dondo’ (code number 9604 in the photograph) and ‘Cape Daisy Congo’ (Congo in the photograph).
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 tempertures 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.
