Asexual reproduction by vegetative cuttings was first conducted in November 2000 in George East, South Africa.

Tests & Trials: Tests and trials were conducted in a poly house during the summer of 2007 in St. Thomas, Ontario. Trials included 15 plants of each variety. All plants were grown from rooted cuttings planted in 11 cm pots on July 10, 2007. Observations and measurements were taken from 10 plants of each variety on September 11, 2007. Colour measurements were made using the 2001 RHS Colour Chart.
