Abstract

A new and distinct cultivar of Diascia plant named ‘Pinkwsm’, characterized by its upright, outwardly spreading, and compact plant habit; freely and continuous branching; and numerous red purple-colored flowers.

Description

Botanical classification/cultivar designation: Diascia×hybrida cultivar Pinkwsm.
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 Pinkwsm.
The new Diascia is a product of a planned breeding program conducted by the Inventor in Guadalupe, Calif. The objective of the breeding program is to create new Diascias with numerous flowers with attractive coloration and good garden performance.
The new Diascia originated from a cross made by the Inventor during the summer of 1998 of the Diascia×hybrida cultivar Ruby Fields, not patented, as the female, or seed parent, with the Diascia×hybrida cultivar Red Start, not patented, as the male, or pollen parent. The new Diascia was selected as a single plant from the resulting progeny by the Inventor during the summer of 1998, in Guadalupe, Calif. on the basis of its attractive flower color.
Asexual reproduction of the new cultivar by cuttings taken in Guadalupe, Calif. since the summer of 1998 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 Pinkwsm 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 ‘Pinkwsm’. These characteristics in combination distinguish ‘Pinkwsm’ as a new and distinct Diascia cultivar:
1. Upright and outwardly spreading plant habit.
2. Freely branching habit.
3. Freely and continuous flowering habit.
4. Red purple-colored flowers.
Plants of the new Diascia are most similar to plants of the parent cultivars. Compared to plants of the female parent, the cultivar Ruby Fields, plants of the new Diascia are more outwardly spreading, are more vigorous, and flower more continuously. In addition, plants of the new Diascia do not set seed whereas plants of the cultivar Ruby Fields set seed. Compared to plants of the male parent, the cultivar Red Start, plants of the new Diascia are more outwardly spreading, are more vigorous, and flower more continuously.
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 ‘Pinkwsm’ grown in a 20-cm container.
The photograph at the bottom of the sheet comprises a close-up view of typical flowering stems, developing flowers, fully opened flowers, and the upper and lower surfaces of typical leaves of ‘Pinkwsm’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown in Encinitas, Calif., in an outdoor nursery under full sunlight conditions during the late winter and early spring with day temperatures averaging 24° C. and night temperatures averaging 12° C. Plants were grown for 16 weeks in 19-cm containers with three plants per container and were pinched one time. Color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
