Origin & Breeding History: The variety 'Lanbor' originated from a cross made by the breeder in March 2001, in West Pugwash, Nova Scotia. The female parent was an unknown commercial seed variety with a trailing habit. The male parent was an unknown commercial seed variety with a compact habit. The new petunia variety was selected as a single plant from the resultant progeny in June 2001. The selection criteria were growth habit, flower colour, male sterility and tolerance to powdery mildew.

Tests & Trials: Tests and trials for 'Lanbor' were conducted in a polyhouse during the spring and summer of 2005 in St. Thomas, Ontario. The trials included a total of 15 plants of each variety. All plants were grown from rooted cuttings, planted into 15 cm pots on March 12, 2005. Observations and measurements were taken from 10 plants of each variety on June 7, 2005. All colour measurements were made using the RHS Colour Chart 2001.
