Torenia plant named ‘Dantorwhite’

Abstract

A new and distinct Torenia plant named ‘Dantorwhite’ particularly characterized by having shiny green foliage, dotted with plenty of delicate, cup shaped flowers in shades of white with a yellow throat; bush cascading, vigorous, compact rounded growth, densely branched; early flowering, flowers all year round in moderate climate; suitable for use as an annual for hanging pots outdoors under partial shade; and good weather tolerance with preferred temperature range of 15-25° C.

Description

Botanical designation: Torenia sp.

Variety denomination: ‘Dantorwhite’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Torenia plant of the Scrophulariaceae family, hereinafter referred to by the cultivar name ‘Dantorwhite’.

The new cultivar originated in a controlled breeding program in Moshav Mishmar Hashiva, Israel. ‘Dantorwhite’ was discovered and selected by the inventor, Gabriel Danziger, as an induced shoot mutation on a single flowering plant of the cultivar ‘Rose Moon’, grown in a controlled, cultivated environment in Moshav Mishmar Hashiva, Israel.

‘Dantorwhite’ is an induced mutant of the cultivar Torenia ‘Rose Moon’ (unpatented), selected in a cultivated environment in Moshav Mishmar Hashiva, Israel. The mutation arose by radiation, as a side shoot, and was stabilized by removing the shoot as a cutting from the mutated sector of the treated parent plant.

Asexual reproduction of the new cultivar by soft tip cuttings was first performed in September, 2002 in Moshav Mishmar Hashiva, Israel and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Dantorwhite’ which in combination distinguish this Torenia as a new and distinct cultivar:

• • 1. Shiny green foliage, dotted with plenty of delicate, cup shaped flowers in shades of white with a yellow throat;
  • 2. Bush cascading, vigorous, compact rounded growth, densely branched;
  • 3. Early flowering, flowers all year round in moderate climate;
  • 4. Suitable for use as an annual for hanging pots outdoors under partial shade; and
  • 5. Good weather tolerance with preferred temperature range of 15-25° C.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘Dantorwhite’ is the parental cultivar Torenia ‘Rose Moon’. Table 1 shows a comparison between ‘Dantorwhite’ and ‘Rose Moon’.

‘Dantorwhite’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant. The following observations, measurements and values describe the new cultivar as grown in Moshav Mishmar Hashiva, Israel under conditions, which closely approximate those generally used in commercial practice.

DETAILED BOTANICAL DESCRIPTION

The following observations, measurements and values describe the new cultivar as grown in Moshav Mishmar Hashiva, Israel under conditions, which closely approximate those generally used in commercial practice. For use as a pot plant, optimal growth conditions include grown outdoors in moderate climate, and indoors during winter. Irrigation and fertilization on a regular basis. The plant is usually grown in full sunlight, but partial shade is required in mid summer. Plants are fully grown in three months from planting a cutting, and blooms all year-round in moderate climate.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), except where general colors of ordinary significance are used. Color values were taken under daylight conditions at approximately noon in Moshav Mishmar Hashiva, Israel in the September 2002 season. The age of the plant described is three months.
