Abstract

A new and distinct cultivar of Diascia plant named ‘Icepole’, characterized by its upright and somewhat outwardly spreading plant habit; freely branching habit; freely and continuous flowering habit; and white-colored flowers.

Description

Botanical classification/cultivar designation: Diascia×hybrida cultivar Icepole.
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 Icepole.
The new Diascia is a product of a planned breeding program conducted by the Inventor in Appleby, Scunthorpe, North Lincolnshire, United Kingdom. The objective of the breeding program is to create new Diascias with good plant vigor and numerous flowers with attractive coloration.
The new Diascia originated from a cross made by the Inventor in 1996 of a proprietary selection of Diascia×hybridaidentified as code number 96L2, not patented, as the female, or seed parent, with the Diascia×hybrida cultivar Ice Cracker, not patented, as the male, or pollen parent. The new Diascia was selected as a single plant from the resulting progeny by the Inventor in 1997, in Appleby, Scunthorpe, North Lincolnshire, United Kingdom on the basis of its plant habit and attractive flower color.
Asexual reproduction of the new cultivar by cuttings taken in Appleby, Scunthorpe, North Lincolnshire, United Kingdom since 1997 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 Icepole 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 ‘Icepole’. These characteristics in combination distinguish ‘Icepole’ as a new and distinct Diascia cultivar:
1. Upright and somewhat outwardly spreading plant habit.
2. Freely branching habit.
3. Freely and continuous flowering habit.
4. White-colored flowers.
Plants of the new Diascia are most similar to plants of the parent selection and cultivar. Plants of the new Diascia differ from plants of the parent selection and cultivar primarily in flower color as flower color of plants of the new Diascia is more intense. In addition, plants of the new Diascia have a more uniform plant habit than plants of the parent selection and cultivar.
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 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 three typical flowering plants of ‘Icepole’ grown in a 20-cm container.
The photograph at the bottom of the sheet comprises a close-up view of typical leaves, flowering stems, developing flowers, and fully opened flowers of ‘Icepole’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in Bonsall, Calif., in an outdoor nursery under full sunlight conditions during the summer with day temperatures ranging from 18 to 35° C. and night temperatures ranging from 7 to 18° C. Plants were grown for about six weeks in 20-cm containers with three plants per container. Color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
