Abstract

A distinct cultivar of Dimorphotheca plant named ‘Purple Blush’, characterized by its upright and mounding growth habit; dark green leaves; freely branching habit; white ray florets with purple bases which gives the appearance of a purple ring at the center of the inflorescence; numerous inflorescences per plant; and relative tolerance to high temperatures.

Description

BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Dimorphotheca plant, botanically known as Dimorphotheca aurantiaca, and referred to by the cultivar name ‘Purple Blush’.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Emerald, Victoria, Australia. The objective of the breeding program was to create new Dimorphotheca cultivars with large inflorescences and attractive ray floret colors.
The new cultivar originated from a cross made by the Inventor of a proprietary selection of Dimorphotheca aurantiaca identified as code No. 92/18 as the female, or seed, parent and a proprietary selection of Dimorphotheca aurantiaca identified as code No. 93/94, as the mole, or pollen, parent. The new Dimorphotheca was selected by the Inventor as a flowering plant within the progeny of this cross in a controlled environment in Emerald, Victoria, Australia in 1995.
Plants of the new cultivar are different from plants of the female parent, the selection 92/18 in leaf size, ray floret color and inflorescence size. Plants of the new Dimorphotheca are larger and have narrower ray florets than plants of the male parent, the selection 93/94. In addition, plants of the new Dimorphotheca have purple-colored ray floret bases whereas plants of both parent selections do not have purple-colored ray floret bases.
Asexual propagation of the new cultivar by terminal cuttings at Emerald, Victoria, Australia, has shown that the unique features of this new Dimorphotheca are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be the unique characterictics of ‘Purple Blush’. These characteristics in combination distinguish ‘Purple Blush’ as a new and distinct cultivar:
1. Upright and mounding growth habit.
2. Dark green leaves.
3. Freely branching habit.
4. White ray florets with purple bases which gives the appearance of a purple ring at the center of the inflorescence.
5. Numerous inflorescences per plant.
6. Relative tolerance to high temperatures.
The cultivar ‘Purple Blush’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.
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 actual colors of the new Dimorphotheca.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Purple Blush’.
The photograph at the bottom of the sheet is a close-up view of a typical inflorescence bud, typical opening inflorescence, typical opened inflorescence, and upper and lower surfaces of typical leaves of ‘Purple Blush’.
DETAILED BOTANICAL DESCRIPTION
The following observations, measurements and values describe 25-cm containers with three plants of the new cultivar grown for about nine to eleven weeks in Bonsall, Calif., under outdoor, full-sun conditions with day temperatures ranging from 21 to 35° C. and night temperatures ranging from 13 to 18° C.
Color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
