Origin & Breeding History: The variety 'PetPre01' originated from a controlled cross pollination made in May 2001 at De Lier, the Netherlands. The female parent was an unnamed proprietary seedling of Petunia integrifolia ssp. inflata and the pollen was from a species plant of Petunia thymifolia. The new variety was initially selected in April 2002 in De Lier, based on plant habit and growth, flower characteristics and drought tolerance. The final selection of 'PetPre01' was made on April 26, 2003.

Tests & Trials: Trials for 'PetPre01' 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 May 25, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
