Osteospermum plant named `Sunny Ingrid`

Abstract

A distinct cultivar of Osteospermum plant named `Sunny Ingrid`, characterized by its upright and outwardly spreading growth habit with dense foliage and erect flower stems; moderate growth rate; purple ray florets with violet blue disc florets; and numerous inflorescences per plant.

Description

The present invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as Osteospermum ecklonis and referred to by the cultivar Sunny Ingrid. The new Osteospermum was tested under the name Sunny Ingrid.

The new cultivar is a product of a planned breeding program conducted by the inventors in Odense, Denmark. The objective of the breeding program was to create new Osteospermum cultivars having uniform plant habit and interesting floret colors and leaf shape.

The new cultivar originated from a cross made by the inventors of two Osteospermum ecklonis proprietary selections. The female, or seed, parent was identified as code number 2.72.93 and the male, or pollen, parent was identified as code number 2.61.93. The new Osteospermum was selected by the inventors from the progeny of this cross in a controlled environment in Odense, Denmark, in 1995. Plants of the new Osteospermum differ from plants of the parent selections in floret color.

Asexual reproduction of the new cultivar by terminal cuttings taken at Odense, Denmark, has shown that the unique features of this new Osteospermum are stable and reproduced true to type in successive generations.

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

1. Upright and outwardly spreading growth habit with dense foliage and erect flower stems.

2. Moderate growth rate.

3. Purple ray florets with violet blue disc florets.

4. Numerous inflorescences per plant. Plants flower continuously.

The cultivar Sunny Ingrid 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.

Plants of the new Osteospermum can be compared to plants of the Osteospermum ecklonis cultivar Sunny Lady (disclosed in U.S. Plant Pat. No. 10,353). However, in side-by-side comparisons conducted in Odense, Denmark, and Keller, Tex., plants of the new Osteospermum were more compact, less spreading, and had stronger and more erect flower stems than plants of the cultivar Sunny Lady. Stems on plants of the cultivar Sunny Lady are purplish red whereas stems of plants of the cultivar Sunny Ingrid are green in color. In addition, peduncles on plants of the cultivar Sunny Lady are reddish towards the apex whereas peduncles of plants of the cultiar Sunny Ingrid are green in color.

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 on the first sheet comprises a side perspective view of a typical flowering plant of `Sunny Ingrid`.

The photograph at the top of the second sheet is a close-up view of typical inflorescences (upper surface, left, and under surface, right) and leaves (center) of `Sunny Ingrid`.

The photograph at the bottom of the second sheet comprises a comparison side perspective view of typical plants the cultivar Sunny Lady (left) and the cultivar Sunny Ingrid (right). Foliage and floret colors in the photographs may appear different from the actual colors due to light reflectance.
