Origin & Breeding History: The variety 'Petlilav' originated from a cross pollination made in August 2004 at Enkhuizen, the Netherlands. The female parent was a lavender coloured proprietary seedling, designated D1353-1 and the male parent a proprietary seedling, designated Z2393-1. The resultant seed was sown in a greenhouse in February 2005 in Enkhuizen. In May 2005, a single plant was selected from the progeny, based on criteria for growth habit, good branching characteristics, flower appearance and size and early flowering.

Tests & Trials: Trials for 'Petlilav' were conducted in a polyhouse during the spring of 2011 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 20, 2011. Observations and measurements were taken from 10 plants of each variety on June 1, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
