Origin & Breeding History: 'Oseclav' originated from a controlled cross made in July, 2001 in Enkhuizen, The Netherlands. The female parent was identified as E0250-1 and the male parent was an unidentified mix of pollen from plants of Osteospermum ecklonis. The new variety was selected from the resultant progeny as a single plant in June 2002, based on criteria for compact plant habit, large flower size and flower colour. Asexual reproduction by cuttings was first conducted in June 2002 in Enkhuizen, The Netherlands.

Tests & Trials: The trials for 'Oseclav' were conducted in a polyhouse at BioFlora in St. Thomas, Ontario, during the spring of 2008. The trials included 15 plants of each variety grown from rooted cuttings and transplanted into 11 cm pots on March 18, 2008. Observations and measurements were taken from 10 plants of each variety on June 3, 2008. All colour characteristics were determined using the 2001 Royal Horticultural Society (RHS) colour chart.
