Origin & Breeding History: 'Bonpriho' originated as an induced branch mutation of proprietary breeding line #127 and was discovered in August 2004 in Yellow Rock, New South Wales, Australia. The plant was further propagated by cuttings and a greenhouse trial was carried out from August 2004 to August 2009 at Bonza Botanicals Pty Limited in Yellow Rock, New South Wales, Australia. The new variety was selected based on plant habit, plant vigour, freely branching habit, strong stems that resist breaking, and foliage and bract colour.

Tests & Trials: The trial for 'Bonpriho' was conducted in 2013 at Schenck's Greenhouses in St. Catharines, Ontario. The trial included 25 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on July 25, 2013. Pots were spaced 30 cm apart from the pot centre. Observations and measurements were taken from 10 plants of each variety on November 27, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
