'Osoutis' is a very early flowering Osteospermum variety with an erect to semi-erect growth habit. The medium green leaves have no variegation and very weak lobing. The flowers of 'Osoutis' are borne on a medium to long peduncle with one or two complete rows of ray florets with incomplete ray floret whorls absent. The ray florets are purple and are elliptic in shape with very slight reflexing of the tips. The main colour of the lower side of the ray florets is red-violet. The disc florets are purple.

Origin & Breeding History: 'Osoutis' arose as the result of a cross of the proprietary seedlings, 'C298'( female parent), with 'C273' (male parent) conducted in Enkhuizen, the Netherlands in 1998. Selection criteria included plant growth habit and vigour, flower colour, shape and size, and plant maturity.

Tests & Trials: Tests and trials for 'Osoutis' were conducted in a polyhouse at BioFlora Inc., St. Thomas, Ontario during the spring of 2004. The trials consisted of fifteen plants of each variety, planted in 11 cm pots. Observations and measured characteristics were taken from 10 plants. Colour determinations were made using the 2001 RHS Colour Chart.
