Abstract

A new and distinct Scabiosa cultivar named ‘SGIPU2-0’ is disclosed, characterized by large, purple-violet colored flowers and unique thick flower stems. The new variety is a Scabiosa, suitable as an outdoor garden or container plant.

Description

Latin name of the genus and species: Scabiosa columbaria.

Variety denomination: ‘SGIPU2-0’.

The new Scabiosa cultivar is the product of a planned breeding program by the inventor John Robb, a citizen of Australia. The breeding program was carried out in Kulnura, New South Wales, Australia. The objective of the breeding program was to develop new Scabiosa varieties with good characteristics for ornamental purposes.

The new variety resulted from the crossing of the seed parent, an unnamed, unpatented proprietary Scabiosa seedling with the pollen parent, an unnamed, unpatented proprietary Scabiosa seedling on February 1 of 2002. The new variety was discovered on February 13 of 2003 by the inventor in a group of seedlings resulting from the 2002 crossing, in a commercial greenhouse in Kulnura, New South Wales, Australia.

Asexual reproduction of the new cultivar ‘SGIPU2-0’ by vegetative cuttings was first performed at a commercial greenhouse in Kulnura, New South Wales, Australia on February 15 of 2003. Subsequently at least five generations have been produced from vegetative cuttings, and have shown that the unique features of this cultivar are stable and reproduced true to type. After observing the new variety confidentially over multiple seasons, the variety was also propagated in tissue culture, in a controlled laboratory, without access by third parties.

SUMMARY OF THE INVENTION

The cultivar ‘SGIPU2-0’ has not 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 ‘SGIPU2-0.’ These characteristics in combination distinguish ‘SGIPU2-0’ as a new and distinct Scabiosa cultivar:

- 1. Purple-Violet colored flowers.
- 2. Distinctive thick flowering stem.
- 3. Large flower size.

COMPARISON TO THE PARENT VARIETIES

Plants of the new cultivar ‘SGIPU2-0’ are similar in most horticultural characteristics to plants of the unnamed, unpatented proprietary seed parent. However, the new variety has a larger overall flower size and thicker flower stem than the seed parent. Also the plant is taller than the seed parent. Additionally, ‘SGIPU2-0’ produce a darker colored flower than the seed parent.

Plants of the new cultivar ‘SGIPU2-0’ are similar in most horticultural characteristics to plants of the unnamed, unpatented proprietary pollen parent. However, the new variety has a larger overall flower size and thicker flower stem than the pollen parent. Also the plant is taller than the pollen parent. Additionally, plants of ‘SGIPU2-0’ produce a much darker colored flower than the pollen parent.

COMPARISON TO COMMERCIAL VARIETY

The new cultivar can be compared to the commercial variety ‘SGIBL01-0’, U.S. plant patent application Ser. No. 13/385,907, currently pending before the USPTO. Plants of the two cultivars are similar in most horticultural characteristics, however, plants of ‘SGIPU2-0’ produce a darker colored flower, with stronger purple coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical flower of ‘SGIPU2-0’.

FIG. 2 illustrates a typical plant of ‘SGIPU2-0’ grown in a greenhouse, in a 6 inch commercial pot. Age of the plant photographed is approximately 30 weeks from a rooted cutting. The photographs were 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
