Abstract

A new and distinct Bougainvillea cultivar named ‘Rijnbo0802’ is disclosed, characterized by backwardly arching bracts that are large, long and slender as well as light purple in color. Plants produce leaves that are long and slender. The new variety is a Bougainvillea, typically produced as an ornamental plant.

Description

Latin name of the genus and species: Bougainvillea communis.
Variety denomination: ‘Rijnbo0802’.
BACKGROUND OF THE INVENTION
The new cultivar is the product of a planned breeding program. The new variety originated as a seedling selection resulting from the crossing of 2 proprietary Bougainvillea communis seedlings identified as ‘21’ as the female or seed parent with ‘52’ as the male or pollen parent.
The new variety was finally selected by the inventor at a commercial greenhouse belonging to the inventor in De Lier, The Netherlands in June of 2008. After this selection the inventor continued confidential testing and propagation of ‘Rijnbo0802’ for approximately 2 years, assessing stability of the unique characteristics of this variety.
Asexual reproduction of the new cultivar ‘Rijnbo0802’ was first performed at the commercial greenhouse of the inventor in De Lier, The Netherlands by vegetative cuttings in November of 2008. Access to all plants was restricted, as plants were kept in a locked greenhouse not open to the public. Through subsequent propagation by vegetative cuttings, multiple generations have been reproduced, which have shown that the unique features of this cultivar are stable and reproduced true to type.
SUMMARY OF THE INVENTION
The cultivar ‘Rijnbo0802’ 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 ‘Rijnbo0802.’ These characteristics in combination distinguish ‘Rijnbo0802’ as a new and distinct Bougainvillea cultivar:
    • 1. Bracts are large, long and slender.
    • 2. Color of mature bract is a light purple.
    • 3. Bracts arch slightly backwards.
    • 4. Leaves are long and slender.
PARENT COMPARISON
Plants of the new cultivar ‘Rijnbo0802’ are similar to the seed parent, in most horticultural characteristics. The new variety, however, produces bracts that are longer and more slender as well as arching backwards more than seen in the parent variety. The new variety also produces a larger and less dense inflorescence compared to the parent.
Plants of the new cultivar ‘Rijnbo0802’ are similar to the pollen parent, in most horticultural characteristics. The new variety, however, produces bracts of a different shape and color than the pollen parent.
COMMERCIAL COMPARISON
‘Rijnbo0802’ is similar in most horticultural characteristics to the variety Bougainvillea communis ‘Vera Pink’ U.S. Plant Pat. No. 15,429 in most horticultural characteristics. The new variety produces flowers bracts that are more purple colored, and lightercolored. Additionally, bracts are larger and longer than ‘Vera Pink’. The new variety also produces leaves that are longer and narrower than ‘Vera Pink’.
‘Rijnbo0802’ is similar in most horticultural characteristics to the variety Bougainvillea communis ‘Rijnbo710’, U.S. Plant Pat. No. 21,009. The new variety produces flowers bracts that are larger and longer than bracts of ‘Rijnbo710’. The new variety produces bracts that are light purple colored, whereas ‘Rijnbo710’ produce bracts that are magenta colored. The new variety also produces leaves that are longer and narrower than ‘Rijnbo710’.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘Rijnbo0802’ grown in a commercial greenhouse in De Lier, The Netherlands. This plant is approximately 6 months old, shown planted in a 14 cm. container. 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.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart 2001, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe a ‘Rijnbo0802’ plant. This plant was grown in a greenhouse in a commercial 17 cm container in De Lier, the Netherlands. The plant described is approximately 1 year old, was not free branching. Branches were regularly pinched and twined on a wooden rack. Temperatures ranged from 15° C. at night and 18° C. to 24° C. during the day. No artificial light, photoperiodic treatments were given to the plants. No chemical treatments were used on the plants. Measurements and numerical values represent averages of typical plant types.
