Title: Variety of Sutera plant named ‘Sumsut 06’

Description:
Botanical classification:  Sutera roth.    
   Varietal denomination: ‘Sumsut 06’. 
   BACKGROUND OF THE INVENTION 
   The present invention comprises a new and distinct cultivar of  Sutera  plant known by the varietal name ‘Sumsut 06’. The new variety was discovered in June of 2005 in a selected breeding program in &#39;s Gravenzande, The Netherlands. The purpose of the breeding program was to develop double-flowering  Sutera  plants with large flowers. 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 2-34. The double-flowering characteristic of the new variety is similar to its parents, but the new variety exhibits a different flower color and larger flowers when compared to both parents. The new variety was first asexually reproduced in September of 2005 by tip cuttings in &#39;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 06’ as a new and distinct cultivar from other  Sutera  varieties known to the breeder.
         Big and double flowers;   Hanging growth habit; and   Three stigmas per flower.       

   The new variety exhibits double flowers like  Sutera  variety ‘Sumsut 05’ (U.S. Plant patent application Ser. No. 12/284,404, applied for concurrently). However, ‘Sumsut 06’ has white flowers and a hanging growth habit, while ‘Sumsut 05’ has violet flowers and a compact growth habit. The following Table 1 provides a comparative listing of botanical characteristics of ‘Sumsut 06’ and ‘Sumsut 05’.

   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 outside in a 37 cm container and was 20 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.
