Abstract

A new and distinct cultivar of Diascia plant named ‘Sunjodi 045’, characterized by its semi-upright and mounding plant habit; strong flowering stems; early and long flowering period; numerous large salmon pink-colored flowers; and good garden performance.

Description

Botanical designation: Diascia hybrida.

Cultivar denomination: ‘SUNJODI 045’.

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 ‘Sunjodi 045’.

The new Diascia plant is a product of a planned breeding program conducted by the Inventor in St. Brides, Netherwent, Monmouthshire, United Kingdom. The objective of the breeding program is to create new freely flowering Diascia plants with strong flowering stems and large attractive flowers.

The new Diascia plant originated from a cross-pollination conducted by the Inventor on Jun. 7, 2008 in St. Brides, Netherwent, Monmouthshire, United Kingdom of a proprietary selection of Diascia hybrida identified as code number d484, not patented, as the female, or seed, parent and with a proprietary selection of Diascia hybrida identified as code number d0912, not patented, as the male, or pollen, parent. The new Diascia plant was discovered and selected by the Inventor 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 combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Sunjodi 045’. These characteristics in combination distinguish ‘Sunjodi 045’ as a new and distinct Diascia plant:

- 1. Semi-upright and mounding plant habit.
- 2. Strong flowering stems.
- 3. Early and long flowering period.
- 4. Numerous large salmon pink-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 hybrida ‘Sunjodiora’, disclosed in U.S. Plant Pat. No. 24,869. In side-by-side comparisons conducted in St. Brides, Netherwent, Monmouthshire, United Kingdom, plants of the new Diascia differed primarily from plants of ‘Sunjodiora’ in the following characteristics:

- 1. Plants of the new Diascia were not as upright as plants of ‘Sunjodiora’.
- 2. Plants of the new Diascia had smaller leaves than plants of ‘Sunjodiora’.
- 3. Plants of the new Diascia had fewer flowers per inflorescence than plants of ‘Sunjodiora’.
- 4. Plants of the new Diascia and ‘Sunjodiora’ differed in flower color as plants of ‘Sunjodiora’ had orange red-colored flowers.

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 top perspective view of a typical flowering plant of ‘Sunjodi 045’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Sunjodi 045’.

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. During the production of the plants, day temperatures averaged 23° C. and night temperatures averaged 13° C. Plants were four months old when the description was taken and five months old when the photographs were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
