Origin & Breeding History: 'Lavender Skies' originated as a chance seeding discovered by the breeder in the summer of 2006, in Pugwash, Nova Scotia. The new Petunia was selected based on growth habit, early flowering, number of flowers and flower colour. 'Lavender Skies' was first propagated by vegetative cuttings in October 2006, in Pugwash, Nova Scotia.

Tests & Trials: Trials for 'Lavender Skies' were conducted in a polyhouse during the spring of 2010 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 27, 2010. Observations and measurements were taken from 10 plants of each variety on June 7, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
