Summary: 'Osjamspowit' differs from the reference variety, 'Balserwibli', mainly in leaf length, portion of the ray floret that is rolled, colour of the lower side of the ray floret and disc colour before dehiscence. The leaves of 'Osjamspowit' are very long whereas they are medium in length in 'Balserwibli'. In 'Osjamspowit', approximately two thirds of the ray floret margin is rolled whereas approximately only one third is rolled in 'Balserwibli'. The main colour of the lower side of the ray floret of 'Osjamspowit' is lighter violet at the apex (spoon), purple red in the middle (constricted zone) and white at the base whereas, in 'Balserwibli', they are brown-violet at the apex (spoon), red-brown in the middle (constricted zone), and violet at the base.

Origin & Breeding History: 'Osjamspowit' originated from the cross 'E0127-1', as the female parent, with a mix of pollen from unidentified male Osteospermum ecklonis plants. The controlled cross was conducted in July 2000 in Enkhuizen, the Netherlands. 'Osecspovan' was selected from the resultant progeny as a single plant in June 2001 based on flower quality, spooned petal shape and flower colour. Asexual reproduction by cuttings was first conducted in June 2001 in Enkhuizen, the Netherlands.

Tests & Trials: The trials for 'Osjamspowit' were conducted in a polyhouse at BioFlora in St. Thomas, Ontario, during the spring of 2007. 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.
