Origin & Breeding History: 'Lan Redtwo' originated from a cross made in Gilroy, California, USA in June 2002. The female parent was a proprietary line with red coloured flowers and the male parent was a proprietary line with purple flowers. The resultant F1 seed was sown in a greenhouse in October 2002. In December 2002 a single plant was selected based of flower colour, form and plant habit.

Tests & Trials: 'Lan Redtwo' was tested in a polyhouse during the summer of 2005, in St. Thomas, Ontario. The trial included 15 plants of the candidate and reference varieties. Rooted cuttings were transplanted into 15 cm pots on April 25, 2005. All colour measurements were made using the RHS Colour Chart 2001. Measured characteristics were based on ten plant measurements.
