Origin & Breeding History: 'Renhy' was developed in Garron, France from a seedling descended from the Hydrangea variety 'Unique' discovered in 1987. 'Renhy' was selected in 2002 after multiple cycles of sibling crosses. The new variety was selected based on its long bloom period, and flower colour that transitions from white, to pink and then to red in the early summer.
Tests & Trials: Trials for 'Renhy' were conducted in an outdoor container trial during the summer of 2009 in St. Thomas, Ontario. The trial included 10 plants of the candidate variety and reference variety. All plants were grown from rooted cuttings transplanted into 7.6 litre containers in the spring of 2008. Trials were arranged with 1/2 meter spacing between plants. Observations and measurements were taken from 10 plants of each variety on June 1, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
