Title: Bougainvillea plant named ‘RIJNBO710’

Description:
Latin name of the genus and species:  Bougainvillea spectabilis.    
   Variety denomination: ‘RIJNBO710’. 
   BACKGROUND OF THE INVENTION 
   The new cultivar is the product of a planned breeding program under the direction of the inventor, Leonardus van Rijn, a citizen of Holland. The objective of the breeding program was to produce plants of  Bougainvillea spectabilis  with compact plant habits. The new variety is a naturally occurring whole plant mutation of the variety  Bougainvillea spectabilis  ‘Vera Deep Purple,’ U.S. Plant Pat. No. 15,429. The new variety was discovered May 2006 by the inventor in a commercial greenhouse, in De Lier, the Netherlands. 
   Asexual reproduction of the new cultivar ‘RIJNBO710’ by vegetative cuttings was performed in De Lier, the Netherlands, in November 2006 and has shown that the unique features of this cultivar are stable and reproduced true to type through several successive generations. 
   SUMMARY OF THE INVENTION 
   The cultivar ‘RIJNBO710’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. 
   The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘RIJNBO710’ These characteristics in combination distinguish ‘RIJNBO710’ as a new and distinct  Bougainvillea spectabilis  cultivar:
         1. Compact plant.   2. Strong plant with branches resistant to breakage.   3. Distinctive purple flower coloration.       

   PARENT COMPARISON 
   Plants of the new cultivar ‘RIJNBO710’ are similar to plants of the parent variety, ‘Vera Deep Purple,’ U.S. Plant Pat. No. 15,429 in most horticultural characteristics, however, plants of the new cultivar ‘RIJNBO710’ produce flowers that are thicker, stronger and more durable than the parent variety. Flowers of the new variety also last longer on the plant than flowers of the parent variety. Additionally, the new variety produces leaves that are thicker and more durable than the parent variety. 
   The parent variety is also the best commercial comparison. 

   
     BRIEF DESCRIPTION OF THE PHOTOGRAPH 
     The accompanying photograph in  FIG. 1  illustrates in full color a typical plant of ‘RIJNBO710’ grown in a greenhouse. The pot size is a commercial 17 cm container, approximately. The plant shown is approximately 1 year old. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
