USPP15964P2 - Diascia plant named ‘Kiedithree’ - Google Patents

Abstract

A new and distinct cultivar of Diascia plant named ‘Kiedithree’, characterized by its compact and outwardly spreading to trailing plant habit; freely branching habit; freely flowering habit; light red-colored flowers with darker red-colored centers; and long flowering period.

Description

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

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 Kiedithree.

The new Diascia is a product of a planned breeding program conducted by the Inventor in Ambacht, The Netherlands. 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 2000 of two unnamed proprietary Diascia×hybrida seedling selections, not patented. The new Diascia was selected as a single plant from the resulting progeny of the cross-pollination by the Inventor in 2000 in an controlled environment in Ambacht, The Netherlands.

Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Ambacht, The Netherlands since 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 Kiedithree 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 ‘Kiedithree’. These characteristics in combination distinguish ‘Kiedithree’ as a new and distinct cultivar of Diascia:

• • 1. Compact and outwardly spreading to trailing plant habit.
  • 2. Freely branching habit.
  • 3. Freely flowering habit.
  • 4. Light red-colored flowers with darker red-colored centers.
  • 5. Long flowering season.

Plants of the new Diascia are more freely flowering than plants of the parent selections. In addition, plants of the new Diascia and the parent selections differ in flower color as plants of the parent selections have pink-colored flowers.

Plants of the new Diascia can be compared to plants of the cultivar Pink Queen, not patented. In side-by-side comparisons conducted in Ambacht, The Netherlands, plants of the new Diascia differed from plants of the cultivar Pink Queen in the following characteristics:

• • 1. Plants of the new Diascia were more freely flowering than plants of the cultivar Pink Queen.
  • 2. Plants of the new Diascia had larger flowers than plants of the cultivar Pink Queen.
  • 3. Plants of the new Diascia and the cultivar Pink Queen differed in flower color as plants of the cultivar Pink Queen had pink-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 bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Kiedithree’ grown in a container.

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

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Lompoc, Calif., in a polycarbonate-covered greenhouse during the winter with day temperatures ranging from 21 to 24° C., night temperatures ranging from 15 to 18° C., and light levels ranging from 4,000 to 8,000 foot candles. Plants were grown for about seven weeks with one plant per 12.5-cm container.
