Origin & Breeding History: 'Sevamil' was discovered as a naturally occurring whole plant mutation of the osteospermum variety 'Seikilrem'. The new variety was discovered and selected by the breeder in June, 2000 based on its unique ivory coloured flowers. Asexual reproduction of the new variety by vegetative tip cuttings was first conducted in August, 2000 in Denmark.

Tests & Trials: Trials for 'Sevamil' were conducted in a polyhouse during the winter-spring of 2003, in St. Thomas, Ontario. The trials included 15 plants per variety. Rooted cuttings were planted in 11.5 cm pots on February 18, 2003. Measured characteristics were based on ten measurements and colour determinations were made using the 2001 RHS colour chart.
