Origin & Breeding History: The variety 'Britena' originated from an open pollinated cross made in Enkhuizen, The Netherlands in the spring of 2004. The female parent was a proprietary variety designated G0809-2, characterized by rose coloured flowers without an eye. The male parent was unknown. The new variety was selected as a single seedling in the late fall of 2004 based on criteria that included flower colour, plant habit and production characteristics.

Tests & Trials: Trials for 'Britena' were conducted in a polyhouse during the spring of 2010, in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 11 cm pots on May 4, 2010. Observations and measurements were taken from 10 plants of each variety on June 4, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
