'Bailmacfive' was first propagated asexually by softwood cuttings in July 2014, in Watkinsville, Georgia, USA.
Tests & Trials: The comparative trial for 'Bailmacfive' was conducted in a polyhouse during the spring and summer of 2020, at BioFlora Inc., in St. Thomas, Ontario. The trial included 10 shrubs each of the candidate and reference varieties. All shrubs were grown from bareroot plant and transplanted into 14 litre containers on May 2020. The observations and measurements were taken from 10 plants or parts of plants of each variety on July 16, 2020. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
