The plants of 'Osecspovan' are medium to tall whereas they are short to medium in height in 'Aksis' and very short to short in 'Aknam'. The leaves of 'Osecspovan' are long to very long whereas they are medium in length in both reference varieties. 'Osecspovan' has fewer ray florets in a whorl than both reference varieties. The lower side of the ray floret of 'Osecspovan' is yellowish white whereas it is light yellow in 'Aksis' and yellow in 'Aknam'.

Origin & Breeding History: 'Osecspovan' originated from the cross 'D0434-1', as the female parent, with a mix of pollen from unidentified male Osteospermum ecklonis plants. The controlled cross was conducted in July 2001 in Enkhuizen, the Netherlands. 'Osecspovan' was selected from the resultant progeny as a single plant in June 2002 based on plant habit, flower type and flower colour. Asexual reproduction by cuttings was first conducted in June 2002 in Enkhuizen, the Netherlands.

Tests & Trials: The trials for 'Osecspovan' 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.
