Abstract

A new and distinct cultivar of Diascia plant named `Strawberry Sundae`, characterized by its compact, open and uniform growth habit; freely basally branching plant habit, plants do not require pinching; and numerous bright pink flowers that are about 2 cm in length and 2.4 cm in width.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Diascia plant, botanically known as Diascia barberae hybrid and referred to by the cultivar name `Strawberry Sundae`.
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 program is to create new Diascia cultivars that flower early, are basally branching, have uniform plant habit and attractive flower color.
The new Diascia originated from a cross by the Inventor in 1992 of an unidentified selection of Diascia barberae as the female, or seed, parent with the nonpatented Diascia barberae cultivar `Lilac Belle` as the male, or pollen, parent. The cultivar `Strawberry Sundae` was discovered and selected by the Inventor in 1993 as a flowering plant within the progeny of the stated cross in a controlled environment in Cobbitty, New South Wales, Australia.
Asexual reproduction of the new Diascia by terminal cuttings taken in a controlled environment in Cobbitty, New South Wales, Australia, has shown that the unique features of this new Diascia are stable and are reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The new Diascia 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.
The following characteristics have been repeatedly observed and are determined to be basic characteristics of `Strawberry Sundae` and distinguish `Strawberry Sundae` as a new and distinct cultivar:
1. Compact, open and uniform growth habit.
2. Freely basally branching plant habit, plants do not require pinching.
3. Numerous bright pink flowers that are about 2 cm in length and 2.4 cm in width.
Compared to plants of the female parent, the unidentified selection of Diascia barberae, plants of the new Diascia are more compact, have smaller flowers, and differ in flower color.
Compared to plants of the male parent, the cultivar `Lilac Belle`, plants of the new Diascia are more upright, flower earlier, have larger flowers and differ in flower color.
Plants of the new Diascia can be compared to nonpatented Diascia cultivar `Ruby Fields`. However, in side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Diascia are more compact and differ in flower color.
Plants of the new Diascia can also be compared to nonpatented Diascia cultivar `Elliots`. However, in side-by-side comparisons conducted in Cobbitty, New South Wales, Australia, plants of the new Diascia have finer stems, finer leaves and flower earlier.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Diascia, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.
The photograph on the first sheet comprises a top perspective view of a typical potted plant of `Strawberry Sundae`.
The photograph on the second sheet comprises a closeup view of typical flowering stems of `Strawberry Sundae`. Flower and foliage colors in the photographs may appear different from the actual colors due to light reflectance.
DETAILED BOTANICAL DESCRIPTION
The following observations, measurements, values, and comparisons describe plants grown in Bonsall, Calif., under outdoor full-sun conditions with day temperatures ranging from 18 to 35° C., 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.
