Diascia plant named ‘CODI101’

Abstract

A new and distinct cultivar of Diascia plant named ‘CODI101’, characterized by its compact, dense, upright and outwardly spreading plant habit; freely flowering habit; and blue violet-colored flowers.

Description

Botanical designation: Diascia×hybrida.

Cultivar denomination: ‘CODI101’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Diascia, botanically known as Diascia×hybrida, and hereinafter referred to by the name ‘CODI101’.

The new Diascia is a product of a planned breeding program conducted by the Inventor in Cobbitty, New South Wales, Australia The objective of the breeding program is to create new freely-flowering Diascia cultivars with uniform plant habit and attractive flower colors.

The new Diascia originated from a cross-pollination made by the Inventor in Cobbitty, New South Wales, Australia in September, 2001 of a proprietary selection of Diascia×hybrida identified as code number X99.46.1, not patented, as the female, or seed, parent with a proprietary selection of Diascia×hybrida identified as code number X99.46.4, not patented, as the male, or pollen, parent. The cultivar CODI101 was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Cobbitty, New South Wales, Australia in October, 2002.

Asexual reproduction of the new Diascia by terminal cuttings in a controlled environment in Macquarie Fields, New South Wales, Australia since October, 2002, has shown that the unique features of this new Diascia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar CODI101 has 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 ‘CODI101’. These characteristics in combination distinguish ‘CODI101’ as a new and distinct cultivar of Diascia:

• • 1. Compact, dense, upright and outwardly spreading plant habit.
  • 2. Freely flowering habit.
  • 3. Blue violet-colored flowers.

Plants of the new Diascia can be compared to plants of the female parent selection. Plants of the new Diascia differ from plants of the female parent selection primarily in flower size as 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 flower color as plants of the new Diascia have more reddish-colored flowers.

Plants of the new Diascia can be compared to plants of the Diascia×hybrida cultivar Codiared, disclosed in U.S. Plant Pat. No. 13,176. In side-by-side comparisons conducted in Macquarie Fields, New South Wales, Australia, plants of the new Diascia differed primarily from plants of the cultivar Codiared in flower color as plants of the cultivar Codiared had red purple-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Diascia, 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 at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘CODI101’ grown in a container.

The photograph at the top of the sheet comprises a close-up view of typical flowers of ‘CODI101’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in Encinitas, Calif. in 12.5-cm containers in an outdoor nursery during the summer and under conditions which closely approximate commercial production. During the production of the plants, day temperatures averaged 24° C., night temperatures averaged 12° C. and light levels averaged 6,000 footcandles. Plants were pinched twice and were about 14 weeks old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
