Origin & Breeding History: 'Kirilo LV63' is a product of a planned breeding program conducted by the breeder of Kirin Brewery Company Ltd., Tokyo, Japan. 'Kirilo-LV63' originated from a cross made in March 2003 in Tochigi, Japan, between an unnamed proprietary selection of L. richardsonii as the female parent, and an unnamed proprietary selection of L. erinus as the male parent. The initial selection was in October 2003 based on growth habit, freely branching, sterility, vigorous growth, and good heat and weather tolerance.

Tests & Trials: Tests and trials were conducted in the summer of 2006 in St. Thomas, Ontario. Trials consisted of 15 plants of each variety, each individually grown in 11cm pots in a polyhouse. Observations and measurements were taken from 10 plants of each variety. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
