Osteospermum plant named ‘Sumipas 01’

Abstract

A new and distinct cultivar of Osteospermum plant named ‘Sumipas 01’, characterized by its upright, outwardly spreading, compact and mounded plant habit; freely branching habit; freely, early and continuous flowering habit; and inflorescences with light purple-colored ray florets.

Description

Botanical designation: Osteospermum ecklonis.

Botanical denomination: ‘Sumipas 01’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as Osteospermum ecklonis, and hereinafter referred to by the name ‘Sumipas 01’.

The new Osteospermum is a product of a planned breeding program conducted by the Inventor in Lüdinghausen, Germany. The objective of the breeding program was to create new compact and early flowering Osteospermum cultivars with large and attractive inflorescences.

The new Osteospermum originated from a cross-pollination in April, 2001 of a proprietary Osteospermum ecklonis selection identified as code number 24, not patented, as the female, or seed, parent with the Osteospermum ecklonis cultivar Sumlight, not patented, as the male, or pollen, parent. The new Osteospermum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Lüdinghausen, Germany in April, 2002.

Asexual reproduction of the new Osteospermum by terminal vegetative cuttings was first conducted in Lüdinghausen, Germany in May, 2002. Asexual reproduction by cuttings 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 cultivar ‘Sumipas 01’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sumipas 01’. These characteristics in combination distinguish ‘Sumipas 01’ as a new and distinct Osteospermum:

• • 1. Upright, outwardly spreading, compact and mounded plant habit.
  • 2. Freely branching habit.
  • 3. Freely, early and continuous flowering habit.
  • 4. Inflorescences with light purple-colored ray florets.

Plants of the new Osteospermum differ primarily from plants of the female parent selection in flowering time as plants of the new Osteospermum flower about 10 days earlier than plants of the female parent selection. Plants of the new Osteospermum differ primarily from plants of the male parent, the cultivar Sumlight in plant size as plants of the new Osteospermum are more compact than plants of the cultivar Sumlight.

Plants of the new Osteospermum can be compared to plants of the cultivar Osjotis, disclosed in U.S. Plant Pat. No. 15,577. In side-by-side comparisons, plants of the new Osteospermum differed from plants of the cultivar Osjotis in the following characteristics:

• • 1. Plants of the new Osteospermum were larger than plants of the cultivar Osjotis.
  • 2. Plants of the new Osteospermum had thicker stems than plants of the cultivar Osjotis.
  • 3. Plants of the new Osteospermum had larger leaves than plants of the cultivar Osjotis.
  • 4. Plants of the new Osteospermum were more freely flowering than plants of the cultivar Osjotis.
  • 5. Plants of the new Osteospermum and the cultivar Osjotis differed in ray floret coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Osteospermum showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Osteospermum. The photograph comprises a side perspective view of a typical flowering plant of ‘Sumipas 01’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

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

The aforementioned photograph, following observations and measurements describe plants grown in Lüdinghausen, Germany in an outdoor nursery during the spring and summer and under commercial production practices. Plants were about three months from planting rooted young plants when the photograph and description were taken. During the production of the plants, day temperatures ranged from 16° C. to 30° C. and night temperatures ranged from 8° C. to 14° C. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
