Sutera plant named ‘Suttipp’

Abstract

A new cultivar of Sutera plant named ‘Suttipp’ that is characterized by medium green leaves, white flowers and a ball-shaped habit. In combination these traits set ‘Suttipp’ apart from all other existing varieties of Sutera known to the inventor.

Description

Genus: Sutera.

Species: cordata.

Denomination: Suttipp.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sutera known botanically as Sutera cordata and referred to hereinafter by the culivar name ‘Suttipp’. ‘Suttipp’ is a hybrid plant grown for use as an ornamental container plant and hanging basket.

The new cultivar ‘Suttipp’ resulted from a formal breeding program in which the criteria was to produce new Sutera plants that produce larger flowers than existing varieties. ‘Suttipp’ was bred by crossing the female parent Sutera ‘P08’ (not patented) with the male parent Sutera ‘SF27’ (not patented). ‘Suttipp’ is distinquishable from its female parent Sutera ‘P08’ (not patented) by having larger flowers and from its male parent Sutera ‘SF27’ (not patented) by having larger flowers. The induced cross was conducted in July 1997 by the inventor in a cultivated area of Naaldwijk, The Netherlands. ‘Suttipp’ was selected by the inventor in April 1998 in Naaldwijk, The Netherlands. Selection was based on the ball-shaped growth habit and medium to large sized flowers.

‘Suttipp’ is characterized by a ball-shaped growth habit, compact internodes, white flowers and green leaves. The closest comparison plants are Sutera ‘Blizzard’ (U.S. Plant Pat. No. 10,966) and Sutera ‘White Showers’ (not patented). ‘Suttipp’ is distinguishable from ‘Blizzard’ by its pattern of initially growing upright and later growing prostrate, its compact habit, leaves that are darker green in color, larger and more lustrous and flowers that are brighter white in color. ‘Suttipp’ is distinguishable from ‘White Showers’ by foliage that is conspicuously toothed and flowers that are 2-3 mm. larger than the flowers of ‘White Showers’.

The first asexual reproduction of ‘Suttipp’ was conducted by the inventor in a cultivated area of Naaldwijk, The Netherlands in September 1998. The method used for asexual propagation was cuttings taken from the shoots. The characteristics of the new cultivar have been determined one hundred percent stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new Sutera cultivar ‘Suttipp’. These traits in combination distinguish ‘Suttipp’ from all other commercial varieties known to the inventor. ‘Suttipp’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic and cultural conditions.

1. Sutera ‘Suttipp’ exhibits a ball-shaped growth habit.

2. Sutera ‘Suttipp’ exhibits medium sized mid-green lustrous foliage.

3. Sutera ‘Suttipp’ exhibits medium to large white flowers with fused petals and a campanulate tube.

4. Sutera ‘Suttipp’ is 50-80 cm. in width and 20 cm. in height at maturity.

5. Sutera ‘Suttipp’ is propagated by cuttings taken from the shoots.

6. Sutera ‘Suttipp’ is an ornamental suitable for containers and hanging baskets.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings illustrate the distinguishing traits of the new cultivar ‘Suttipp’. The drawing on sheet 1 illustrates the entire plant in bloom from a side perspective. The drawing on sheet 2 is a close-up view of the flowers and leaves. The drawing on sheet 3 illustrates a typical Sutera flower being held adjacent to a flower on a Sutera ‘Suttipp’ plant. The drawings were made using conventional techniques and although colors may appear different from actual colors due to light reflectance they are as accurate as possible by conventional photography.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the Sutera cultivar named ‘Suttipp’. Data was collected in Arroyo Grande, Calif. from plants grown in 2-litre containers out-of-doors in full sun. The plants were approximately 18-months-old at the time. The color determinations are in accordance with The 2001 R.H.S. Color Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used. Growing conditions, diseases and pests are similar to that of other Sutera. There are no growing problems known to the inventor.
