Origin & Breeding History: 'Osjamvan' originated from a controlled cross made in July 2000, in Enkhuizen, The Netherlands. The female parent was identified as E0053-1 and the male parent was a mix of pollen from unidentified Osteospermum ecklonis plants. The new variety was selected from the resultant progeny as a single plant in June 2001, based on criteria for plant habit and flower colour. Asexual reproduction by cuttings was first conducted in June 2001, in Enkhuizen, The Netherlands.

Tests & Trials: The trials for 'Osjamvan' 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.
