Origin & Breeding History: 'HJ-117' originated from a cross between Hibiscus variety 'Byron Metts' as the female parent and variety 'HJ-136' as the male parent. This hand pollinated cross was conducted by the breeder, Henry Buffinga, at H & J Buffinga Farm in Seaforth, Ontario in November 2002. 'HJ-117' was selected for its colour and the persistance of its flowers.

Tests & Trials: Trials for 'HJ-117' were conducted in a polyhouse during the winter of 2006-2007 at H & J Buffinga Farm in Seaforth, Ontario. There were ten (10) plants of the candidate variety, three (3) plants of reference variety 'HJ-116' and five (5) plants of reference variety 'HJ-04-06'. All plants were grown in 17 cm pots. Measured characteristics were based on measurements taken from 10 plants or parts of plants on April 11, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
