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.
