Diascia plant named ‘Codiblim’

Abstract

A new and distinct cultivar of Diascia plant named ‘Codiblim’, characterized by its compact and upright plant habit; freely branching habit; freely flowering habit; white to light red purple-colored flowers with red purple-colored centers; and good temperature tolerance.

Description

Botanical classification/cultivar designation: Diascia×hybrida cultivar Codiblim.

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 cultivar name Codiblim.

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 compact Diascias with numerous uniquely-colored flowers.

The new Diascia originated from a cross-pollination made by the Inventor in 1999 of the Diascia×hybrida cultivar Codiap, disclosed in U.S. Plant Pat. No. 13,169, as the female, or seed parent, with a proprietary Diascia×hybrida selection identified as X99.54.9, 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 October, 1999, in an controlled environment in Cobbitty, New South Wales, Australia.

Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Cobbitty, New South Wales, Australia since October, 1999 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 Codiblim 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 characteristics of ‘Codiblim’. These characteristics in combination distinguish ‘Codiblim’ as a new and distinct cultivar of Diascia:

1. Compact and upright plant habit.

2. Freely branching habit.

3. Freely flowering habit.

4. White to light red purple-colored flowers with red purple-colored centers.

5. Good temperature tolerance.

Plants of the new Diascia differ primarily from plants of the parents in flower color as plants of the female parent, the cultivar Codiap, have soft orange-colored flowers and plants of the male parent, the selection X99.54.9 have pink-colored flowers.

Plants of the new Diascia can be compared to plants of the Diascia cultivar Codiaw, disclosed in U.S. Plant Pat. No. 13,058. In side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Diascia differed from plants of the cultivar Codiaw in the following characteristics:

1. Plants of the new Diascia were shorter than plants of the cultivar Codiaw.

2. Plant form of the new Diascia was fuller and not as open as plant form of the cultivar Codiaw.

3. Plants of the new Diascia and the cultivar Codiaw differed slightly in flower coloration.

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 at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Codiblim’ grown in a container. The photograph at the bottom of the sheet comprises a close-up view of typical leaves and flowers of ‘Codiblim’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Encinitas, Calif., in an outdoor nursery during the winter and spring with day temperatures averaging 24° C., night temperatures ranging from 12 to 19° C., and light levels about 4,000 to 6,000 foot candles. Plants were grown for about 16 weeks in 12.7-cm containers and were pinched one time.
