Origin & Breeding History: The variety 'Bombshell' was discovered by the breeder in Boskoop, Netherlands in May of 2003. 'Bombshell' originated from a naturally occurring branch mutation on a plant of Hydrangea paniculata 'Grandiflora'. The new variety was selected in 2003 based on the abundance of sterile flowers, sepal colour and form, panicle shape, long bloom period and compact growth habit. Asexual reproduction of the new variety was first conducted by softwood stem cuttings in July 2003 in Boskoop, Netherlands.
Tests & Trials: Trials for 'Bombshell' were conducted during the summer of 2011, in St. Thomas, Ontario. The trial included a total of 10 plants of the candidate variety and 7 plants of the reference variety. All plants were grown from rooted cuttings transplanted into 2 gallon containers in the spring of 2010 and transplanted to the field in the fall of 2010. Observations and measurements were taken from 10 plants of the candidate variety and 7 plants of the reference variety on July 26, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
