plant named ‘SBAWH03-2’

Abstract

A new and distinct Sutera cultivar named ‘SBAWH03-2’ is disclosed, characterized a trailing, compact, plant habit, and very large, abundant white flowers. The new variety is an Sutera, typically produced as a garden or container plant.

Description

Latin name of the genus and species: Sutera cordata.

Variety denomination: ‘SBAWH03-2’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program. The new variety originated from a cross pollination of the seed parent, unpatented proprietary selection of Sutera cordata variety ‘X08.1.1’ with the pollen parent a, unpatented Sutera cordata variety ‘X08.1.3’. The crossing was made during January of 2008, at a research greenhouse in New South Wales Australia. ‘SBAWH03-2’ was discovered by the inventor, Graham Brown, a citizen of Australia, in New South Wales, at the research greenhouse during May of 2008.

Asexual reproduction of the new cultivar ‘SBAWH03-2’ was first performed in New South Wales, Australia, at a research greenhouse by vegetative cuttings in May of 2008. ‘SBAWH03-2’ has since produced several generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘SBAWH03-2’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘SBAWH03-2’. These characteristics in combination distinguish ‘SBAWH03-2’ as a new and distinct Sutera cultivar:

• • 1. Trailing, compact plant habit.
  • 2. Abundant flowering.
  • 3. Very large flower.

PARENTAL COMPARISON

Plants of the new cultivar ‘SBAWH03-2’ are similar to the female parent in most horticultural characteristics. However, ‘SBAWH03-2’ differs in producing larger flowers. Additionally, the new variety shows better resistance to high temperatures.

Plants of the new cultivar ‘SBAWH03-2’ are similar to the male parent in most horticultural characteristics. However, ‘SBAWH03-2’ differs in having a moderately compact and trailing plant habit, whereas the pollen has a distinctively compact plant habit.

COMMERCIAL COMPARISON

‘SBAWH03-2’ can be compared to the commercial variety Sutera cordata ‘Dancop20’ U.S. Plant Pat. No. 19,350. Plants of ‘Dancop20’ are similar to plants of ‘SBAWH03-2’ in most horticultural characteristics, however, ‘SBAWH03-2’ produces a larger flower, and more flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘SBAWH03-2’ grown outdoors in Oxnard, Calif. This plant is approximately 2 months old, shown in a 6 inch pot. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultral Colour Chart, 2001, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘SBAWH03-2’ plants in a commercial greenhouse in Oxnard, Calif. Temperatures ranged from 10° C. to 29° C. night and day. Plants are approximately 3 months old from a rooted cutting. No artificial light, photoperiodic treatments or chemical treatments were given to the plants. Natural light conditions were approximately 2500 to 4000 fc of light. Measurements and numerical values represent averages of typical plant types.
