Description
Botanical classification: Sutera roth.

Varietal denomination: ‘Sumsut 04’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Sutera plant known by the varietal name ‘Sumsut 04’. The new variety was discovered in May of 2005 in a selected breeding program in 's Gravenzande, The Netherlands. The purpose of the breeding program was to develop double-flowering Sutera plants with a variety of colors. 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 2-64. The double-flowering characteristic of the new variety is similar to its parents, but the new variety exhibits a different flower color and a more compact growth habit when compared to both parents. The new variety was first asexually reproduced in July of 2005 by tip cuttings in 's Gravenzande, The Netherlands. The new variety has been trial and field tested and has been found to retain its distinctive characteristics and remains true to type through successive asexual propagations.

The following traits distinguish ‘Sumsut 04’ as a new and distinct cultivar from other Sutera varieties known to the breeder.

    • Double flowers; and
    • Upright and compact growth habit.

The new variety exhibits double flowers like Sutera variety ‘Sumsut 06’ (U.S. Plant patent application Ser. No. 12/284,402, applied for concurrently). However, ‘Sumsut 06’ has white flowers and a hanging growth habit, while ‘Sumsut 04’ has purple flowers and a compact growth habit. The following Table 1 provides a comparative listing of botanical characteristics of Sumsut 04’ and ‘Sumsut 06’.

DESCRIPTION OF THE DRAWING

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

FIG. 1 is a photograph of an 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 The Netherlands. The new variety was grown in a greenhouse in a 12 cm container and was 10 weeks old when described. The color readings were taken indoors under natural light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London.
