The cross took place at Syngenta Seeds B.V., at Enkhuizen, the Netherlands in June, 1999. A single plant was selected in May 2000 based on early flowering, plant growth habit and vigour. Asexual reproduction of 'Petlavve' began in August 2000 in Enkhuizen, the Netherlands.

Tests & Trials: The tests and trials for 'Petlavve' were conducted in a poly-house during the spring of 2005 in St. Thomas, Ontario. The trial included a total of 15 plants of each variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on March 12, 2005. All colour characteristics were determined using the 2001 RHS colour chart. Unless otherwise indicated, measured characteristics were based on ten plant measurements.
