Variety of Sutera plant named ‘Sumsut 03’

Abstract

A new and distinct Sutera plant with white colored double flowers and a long flowering season.

Description

Botanical classification: Sutera cordata.

Varietal denomination: ‘Sumsut 03’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Sutera plant known by the varietal name ‘Sumsut 03’. The new variety was developed in 2004 in a selected breeding program in Lùdinghausen, Germany. The purpose of the breeding program was to develop a Sutera plant with a semi-erect growth habit and long flowering time in the summer. The new variety is a selection from the cross of proprietary unpatented breeding plants. The female parent was Seedling 1-5 and the male parent was Seedling 1-70. The upright to semi-upright growth character of the new variety is similar to its parents but the new variety exhibits double flowers. The new variety was first asexually reproduced in July of 2004 by tip cuttings in Germany. The new variety has been trial and field tested and has been found to retail its distinctive characteristics and remains true to type through successive asexual propagations.

The following traits distinguish ‘Sumsut 03’ as a new and distinct cultivar from other Sutera varieties known to the breeder.

•Double flowers;

•Upright to semi-upright growth habit; and

•Long leaves that are rounded in shape.

Further, the new variety exhibits a similar rooting habit and white flowers like Sutera variety ‘Blizzard’ (U.S. Plant Pat. No. PP10,996). However, ‘Sumsut 03’ exhibits double flowers and ‘Blizzard’ is a single flowering variety.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new variety, with the color being as nearly true as is possible with color illustrations of this type:

FIG. 1 is a close-up photograph of the flowers of the new variety;

FIG. 2 is a photograph of an entire plant of the new variety; and

FIG. 3 is another view of the entire plant of the new variety.

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected by asexual reproductions carried out in Germany. Plants for the description were grown outdoors in a lined 25 cm hanging basket at 25-30° C. daytime temperatures and at 12-15° C. night temperatures. The color readings were taken on a plant outdoors on a sunny day. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London.
