| Abstract: |

| Claim: |
It is claimed:
1. A new and distinct cultivar of Osteospermum plant named `Lanavalia`, as illustrated and described. |
| Description: |
Botanicaldesignation: Osteospermum ecklonis.
Botanical denomination: `Lanavalia`.
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 `Lanavalia`.
The new Osteospermum is a product of a planned breeding program conducted by the Inventor in Tiptree, Essex, United Kingdom. The objective of the breeding program was to create new Osteospermum cultivars with uniform and freely branching planthabit, unique and attractive floret coloration, and tolerance to high temperatures.
The new Osteospermum originated from a cross-pollination during the spring of 2002 of an Osteospermum ecklonis seedling selection identified as code number 09-51-01, not patented, as the female, or seed, parent with an Osteospermum ecklonisseedling selection identified as code number 04-113-00, 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 grownin a controlled environment in Tiptree, Essex, United Kingdom in 2003. The new Osteospermum was selected on the basis of its freely branching habit, attractive ray floret coloration and tolerance to high temperatures.
Asexual reproduction of the new Osteospermum by terminal vegetative 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 Lanavalia 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 ingenotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Lanavalia`. These characteristics in combination distinguish `Lanavalia` as a new and distinct Osteospermum: 1. Compact, upright,somewhat outwardly spreading and mounded plant habit. 2. Freely branching habit. 3. Early and freely flowering habit. 4. Inflorescences with soft orange yellow-colored ray florets. 5. Tolerant to high temperatures.
Plants of the new Osteospermum differ primarily from plants of the parent selections in ray floret coloration.
Plants of the new Osteospermum can be compared to plants of the cultivar Akterra, disclosed in U.S. Plant Pat. No. 14,300. However, in side-by-side comparisons conducted in Tiptree, Essex, United Kingdom, plants of the new Osteospermumdiffered from plants of the cultivar Akterra in the following characteristics: 1. Plants of the new Osteospermum were more compact than plants of the cultivar Akterra. 2. Plants of the new Osteospermum were more freely branching than plants of thecultivar Akterra. 3. Plants of the new Osteospermum had smaller inflorescences than plants of the cultivar Akterra. 4. Plants of the new Osteospermum and the cultivar Akterra differed in ray floret coloration as plants of the cultivar Akterra hadgreyed orange-colored ray florets.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate 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 photographs may differ from thecolor values cited in the detailed botanical description which accurately describe the colors of the new Osteospermum.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of `Lanavalia` grown in a container.
The photograph at the bottom of the sheet is a close-up view of a typical inflorescence of `Lanavalia`.
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 photographs, following observations and measurements describe plants grown in Tiptree, Essex, United Kingdom in a glass-covered greenhouse and under typical production practices. Plants were about five months old when thephotographs and description were taken. Plants were grown in 15-cm containers and were pinched one time. During the production of the plants, day temperatures averaged 19.degree. C. and night temperatures averaged 14.degree. C. In the followingdescription, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
