Abstract

A new and distinct cultivar of Diascia plant named ‘Sunjodiblupi’, characterized by its semi-upright and mounding plant habit; long and strong flowering stems; early and long flowering period; numerous large red purple-colored flowers; and good garden performance.

Description

Botanical designation: Diascia hybrida.
Cultivar denomination: ‘SUNJODIBLUPI’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Diascia plant, botanically known as Diascia hybrida, and hereinafter referred to by the name ‘Sunjodiblupi’.
The new Diascia plant is a product of a planned breeding program conducted by the Inventors in St. Brides, Netherwent, Monmouthshire, United Kingdom. The objective of the breeding program is to create new Diascia plants with long and strong flowering stems and large attractive flowers.
The new Diascia plant originated from a cross-pollination conducted by the Inventors on Jun. 7, 2008 in St. Brides, Netherwent, Monmouthshire, United Kingdom with a proprietary selection of Diascia hybrida identified as code number d6770, not patented, as the female, or seed, parent and with a proprietary selection of Diascia hybrida identified as code number d5233, not patented, as the male, or pollen, parent. The new Diascia plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in St. Brides, Netherwent, Monmouthshire, United Kingdom on Aug. 20, 2008.
Asexual reproduction of the new Diascia plant by vegetative cuttings in a controlled greenhouse environment in St. Brides, Netherwent, Monmouthshire, United Kingdom since Aug. 20, 2008 has shown that the unique features of this new Diascia plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Diascia have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Sunjodiblupi’. These characteristics in combination distinguish ‘Sunjodiblupi’ as a new and distinct cultivar of Diascia plant:
    • 1. Semi-upright and mounding plant habit.
    • 2. Long and strong flowering stems.
    • 3. Early and long flowering period.
    • 4. Numerous large red purple-colored flowers.
    • 5. Good garden performance.
Plants of the new Diascia can be compared to plants of the female parent selection. Plants of the new Diascia differ primarily from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Diascia have longer flowering stems than plants of the female parent selection.
    • 2. Plants of the new Diascia have larger flowers than plants of the female parent selection.
Plants of the new Diascia can be compared to plants of the male parent selection. Plants of the new Diascia differ primarily from plants of the male parent selection in cold hardiness as plants of the new Diascia are more cold hardy than plants of the male parent selection.
Plants of the new Diascia can be compared to plants of the Diascia barbarae ‘Diastu’, disclosed in U.S. Plant Pat. No. 13,949. In side-by-side comparisons conducted in St. Brides, Netherwent, Monmouthshire, United Kingdom, plants of the new Diascia differed primarily from plants of ‘Diastu’ in the following characteristics:
    • 1. Plants of the new Diascia were semi-upright whereas plants of ‘Diastu’ were outwardly spreading.
    • 2. Plants of the new Diascia were taller than plants of ‘Diastu’.
    • 3. Plants of the new Diascia had thicker flowering stems than plants of ‘Diastu’.
    • 4. Plants of the new Diascia had larger leaves than plants of ‘Diastu’.
    • 5. Plants of the new Diascia and ‘Diastu’ differed slightly in flower color.
    • 6. Flower spurs of plants of the new Diascia were positioned towards the flower whereas flower spurs of plants of ‘Diastu’ were positioned away from the flower.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Diascia plant 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 plant.
The photograph at the top of the sheet is a side perspective view of a typical flowering plant of ‘Sunjodiblupi’ grown in a container.
The photograph at the bottom of the sheet is a close-up view of a typical inflorescence of ‘Sunjodiblupi’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown in 15-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial Diascia production.
