Origin & Breeding History: 'Oslipu' was developed by the breeder Anna M.W.P. Houbraken, an employee of Syngenta Seeds B.V. in Enkhuizen, The Netherlands. The new osteospermum variety originated from a cross between female parent 'C 298' and male parent 'C 274', conducted in June 1999. The new variety was selected from the progeny in 2000 based on plant habit, branching and plant vigor. The variety has been propagated by vegetative cuttings since August 2000.
Tests & Trials: The trials for 'Oslipu' were conducted in a polyhouse at BioFlora in St. Thomas, Ontario, during the spring of 2006. The trials included 15 plants of each variety grown from rooted cuttings and transplanted into 11 cm pots. Observations and measurements were taken from 10 plants of each variety. All colour characteristics were determined using the 2001 Royal Horticultural Society (RHS) colour chart.
