Sutera plant named ‘Blisch’

Abstract

A new and distinct Sutera plant named ‘Blisch’ characterized by its large white-colored flowers, dark green-colored foliage and a spreading and trailing growth habit.

Description

Latin name of the genus and species of plant claimed: Sutera cordata.

Variety denomination. ‘Blisch’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sutera plant botanically known as Sutera cordata and hereinafter referred to by the cultivar name ‘Blisch’.

The new cultivar originated in a controlled breeding program during the summer of 2000 at Billerbeck, Germany. The progeny of this breeding were evaluated in the summer of 2001 and one plant among that progeny was selected and eventually named ‘Blisch’. The objective of the breeding program was the development of Sutera cultivars with a trailing habit and large flowers.

The identity of the female (seed) parent of the new cultivar used in the above-described breeding program by the inventor is not known. The identity of the male (pollen) parent of the new cultivar used in the above-described breeding program by the inventor is not known.

Asexual reproduction of the new cultivar by terminal stem cuttings taken since 2001 in West Chicago, Ill., has demonstrated that the new cultivar reproduces true to type with all the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length without, however, any variance in genotype.

It was repeatedly found that the cultivar of the present invention:

• • 1. Exhibits large white-colored flowers,
  • 2. Forms dark green-colored foliage, and
  • 3. Exhibits a spreading and trailing growth habit.

Of the many Sutera cultivars known to the inventor, the most similar to the new cultivar is ‘Novasnow’ (U.S. Plant Pat. No. 12,026). However, in a side-by-side comparison, conducted at West Chicago, Ill., plants of the new cultivar differed from plants of ‘Novasnow’ in the following characteristics:

• • 1. Plants of the new cultivar had smaller leaves than plants of ‘Novasnow’, and
  • 2. Plants of the new cultivar had a larger area of spread than plants of ‘Novasnow’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Blisch’. The plants were grown in 10 cm pots for 9 weeks in a greenhouse at West Chicago, Ill.

FIG. 2 illustrates a close-up view of an individual leaf and flower of ‘Blisch’.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 1995 edition, except where color terms of ordinary significance are used. The color values were determined on Jul. 14, 2003, between 10:30 and 11:30 a.m. under natural daylight conditions.

The following descriptions and measurements describe plants produced from cuttings taken from stock plants and grown in a double polycarbonate-covered greenhouse under conditions comparable to those used in commercial practice. Plants were grown in 10 cm pots for 9 weeks, while utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 65-75° F. during the day and approximately 55-60° F. during the night. Greenhouse light levels were maintained at approximately 4,000-8,000 footcandles during the day.
