Abstract

A new and distinct cultivar of Diascia plant named ‘Sumdia 03’, characterized by its compact, upright and outwardly spreading plant habit; freely branching habit; freely and early flowering habit; intense purplish red-colored flowers; and good temperature tolerance.

Description

Botanical classification/cultivar designation: Diascia elegans cultivar Sumdia 03.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Diascia plant, botanically known as Diascia elegans, and hereinafter referred to by the cultivar name Sumdia 03.
The new Diascia is a product of a planned breeding program conducted by the Inventor in Lüdinghausen, Germany. The objective of the breeding program is to create new early flowering Diascias with numerous flowers, attractive flower coloration and long flowering period.
The new Diascia originated from a cross-pollination made by the Inventor in June, 2002 of a proprietary seedling of Diascia elegans identified as code number 22, not patented, as the female, or seed parent, with a proprietary seedling of Diascia elegans identified as code number 6, not patented, as the male, or pollen parent. The new Diascia was selected as a single plant from the resulting progeny of the cross-pollination by the Inventor in April, 2003, in an controlled environment in Lüdinghausen, Germany.
Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Lüdinghausen, Germany since April, 2003, has shown that the unique features of this new Diascia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Sumdia 03 have 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 charcteristics of ‘Sumdia 03’. These characteristics in combination distinguish ‘Sumdia 03’ as a new and distinct cultivar of Diascia:
    • 1. Compact, upright and outwardly spreading plant habit.
    • 2. Freely branching habit.
    • 3. Freely and early flowering habit.
    • 4. Intense purplish red-colored flowers.
    • 5. Good temperature tolerance.
Plants of the new Diascia differ from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Diascia flower for a longer period of time than plants of the female parent selection.
    • 2. Plants of the new Diascia have darker colored flowers than plants of the female parent selection.
Plants of the new Diascia differ from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Diascia are more freely branching than plants of the male parent selection.
    • 2. Plants of the new Diascia have stronger lateral branches than plants of the male parent selection.
Plants of the new Diascia can be compared to plants of the cultivar Codiared, disclosed in U.S. Plant Pat. No. 13,176. In side-by-side comparisons conducted in Lüdinghausen, Germany, plants of the new Diascia differed from plants of the cultivar Codiared in the following characteristics:
    • 1. Plants of the new Diascia were more compact than plants of the cultivar Codiared.
    • 2. Plants of the new Diascia were more freely branching than plants of the cultivar Codiared.
    • 3. Plants of the new Diascia had smaller leaves than plants of the cultivar Codiared.
    • 4. Plants of the new Diascia flowered about two weeks earlier than plants of the cultivar Codiared.
    • 5. Plants of the new Diascia and the cultivar Codiared differed in flower color as plants of the cultivar Codiared had lighter colored flowers.
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 slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Diascia.
The photograph on the first sheet comprises a top perspective view of a typical flowering plant of ‘Sumdia 03’ grown in a container.
The photograph on the second sheet is a close-up view of typical flowering stems of ‘Sumdia 03’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in Lüdinghausen, Germany, in a glass-covered greenhouse during the spring with day temperatures about 15 to 18° C., night temperatures about 12° C., and light levels about 20,000 to 30,000 lux. Plants were grown for about 12 weeks in 12-cm containers; plants were pinched one time.
