Diascia plant named ‘Coditer’

Abstract

A new and distinct cultivar of Diascia plant named ‘Coditer’, characterized by its upright and somewhat outwardly spreading plant habit; freely branching habit; freely flowering habit; light red-colored flowers; and good temperature tolerance.

Description

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

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 Coditer.

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 flowers and attractive flower coloration.

The new Diascia originated from a cross-pollination made by the Inventor in the spring of 2000 of a proprietary Diascia×hybrida selection identified as code number X99.55.5, not patented, as the female, or seed parent, with a proprietary Diascia×hydrida selection identified as code number X99.62.2, 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 September, 2001, in an controlled environment in Cobbitty, New South Wales, Australia.

Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Cobbitty, New South Wales, Australia since September, 2001 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 Coditer 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 ‘Coditer’. These characteristics in combination distinguish ‘Coditer’ as a new and distinct cultivar of Diascia:

• • 1. Upright and somewhat outwardly spreading plant habit.
  • 2. Freely branching habit.
  • 3. Freely flowering habit.
  • 4. Light red-colored flowers.
  • 5. Good temperature tolerance.

Plants of the new Diascia differ from plants of the female parent selection primarily in flower color as plants of the female parent selection have light orange-colored flowers. Plants of the new Diascia are more compact and flower earlier than plants of the male parent selection.

Plants of the new Diascia can be compared to plants of the cultivar Copiap, disclosed in U.S. Plant Pat. No. 11,488. In side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Diascia differed from plants of the cultivar Copiap in the following characteristics:

• • 1. Plants of the new Diascia were more freely flowering than plants of the cultivar Copiap.
  • 2. Plants of the new Diascia and the cultivar Copiap differed in flower color as plants of the cultivar Copiap had soft orange-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 at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Coditer’ grown in a container.

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

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 averaging 12° C., and light levels about 6,000 foot candles. Plants were grown for about 16 weeks with three plants per one-gallon container; plants were pinched one time.
