Summary: The plants of 'Kasumi' have shorter internodes than those of 'Helen Johnson'. The stems of 'Kasumi' have no thorns while those of 'Helen Johnson' have medium length thorns. The leaves and bracts of 'Kasumi' are smaller than those of 'Helen Johnson'. The inflorescences of 'Kasumi' have many medium to dense bract clusters while those of 'Helen Johnson' have few to medium number of sparse bract clusters. The colours of the inner and outer sides of the young bracts of 'Kasumi' differ from those of both reference varieties.

Description:

PLANT: upright compact growth habit
YOUNG SHOOT: light green with weak anthocyanin colouration
STEM: no thorns

LEAF BLADE: medium ovate, obtuse apex, light to medium green, absent or weak undulation of margin

INFLORESCENCE: auxillary arrangement of bract clusters, many bract clusters, medium to dense bract clusters, flowers present
YOUNG BRACT: outer side when small light yellow brown (RHS 161A), inner side when calyx lobe not open light blue pink (RHS 62C) with tones of light yellow brown (RHS 161D), inner side when calyx lobe open light blue pink (RHS 62C)
BRACT: single, medium ovate, obtuse base, upper side of calyx lobes light yellow brown (RHS 158D) with light blue pink (RHS 65C) on the narrower lobes, inner side when calyx lobe wilted light blue pink (RHS 62C)

Origin & Breeding History: 'Kasumi' orignated as a whole plant mutation of the variety 'Konatu' discovered in July 2004 in an isolated area at Tsushima, Aichi, Japan. The discovered plant was grown in a trial from July 2007 to August 2008 in a controlled environment. The botanical characteristics of the plant were then examined. As a result, it was concluded that this Bougainvillea plant was distiguishable from any other varieties and named 'Kasumi'.

Tests & Trials: Trials for 'Kasumi' were conducted in a polyhouse during the summer of 2012 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cutttings and transplanted into 15 cm shallow pots on May 2, 2012. Observations and measurements were taken from 10 plants of each variety on June 26, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
