Origin & Breeding History: 'Cante Laver' originated from a cross made at Morgan Hill, California, USA, in September, 2001. The female parent was 8961-2, a proprietary line with dark red coloured flowers, and the male parent was 9104-1, a proprietary line with dark red coloured flowers. The resultant seed was sown in 2002 and a single plant was selected based on flower colour, flower form and plant habit.

Tests & Trials: Trials for 'Cante Laver' were conducted in a polyhouse during the summer of 2006 at St. Thomas, Ontario. The trials included 15 plants of the candidate and reference varieties. Rooted cuttings were planted into 4 inch pots on May 1, 2006 and then transplanted into 8 inch pots on June 26, 2006. Measured characteristics were based on 10 measurements. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
