Origin & Breeding History: The hydrangea variety 'Lynn' originated from an open pollination made in Grand Haven, Michigan, USA in July 2003. The pollination was between the female parent 'Bailmer' and an unknown male parent. The new variety was selected from the progeny in May 2005, based on criteria for foliage colour, flowering on new growth without vernalization, inflorescence size and flower colour. Propagation by softwood cuttings was first conducted in June 2005 in Grand Haven, Michigan, USA.

Tests & Trials: Trials for 'Lynn' were conducted in a polyhouse and outdoors during the spring and summer of 2010 in St. Thomas, Ontario. The trial included 15 plants of the candidate variety and 10 of the reference variety. All plants were grown from 10 cm rooted liners which were transplanted into 2 gallon containers on June 3, 2007 and in 3 gallon containers on June 2, 2008. Observations and measurements were taken from 10 plants of each variety on May 31, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
