Origin & Breeding History: 'Abetwo' orginated from an open pollinated cross between the female parent variety 'Annabelle' and pollen from an unknown male parent in Grand Haven, Michigan, United States in 2002. The new Hydrangea variety was developed by the breeder, Timothy D. Wood, an employee of Spring Measow Nursery in Grand Haven, Michigan. 'Abetwo' was selected in 2004 based on stem strength, inflorescence size and largely sterile mophead-type flowers. Asexual reproduction of 'Abetwo' by softwood cuttings was first conducted in 2004 in Grand Haven, Michigan, United States.
Tests & Trials: Trials for 'Abetwo' were conducted in an outdoor irrigated container trial during the summer of 2010, in St. Thomas, Ontario. The trial included a total of 15 shrubs each of the candidate and reference varieties. All shrubs were grown from 'quick turn' potted liners, transplanted into 7.5 liter containers in the spring of 2009. Trials were arranged in rows with 1 m spacing between plants. Due to warm spring temperatures, the trial plants were cut back in May 2010. As a result flower characteristics are smaller in size than typically observed. Observations and measurements were taken from 10 plants of each variety on July 19, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
