A plant was selected from the resultant progeny of the cross in 2001, based on early flowering, flower characteristics and plant habit. Asexual reproduction by vegetative cuttings was first conducted in August, 2001 in Enkhuizen, The Netherlands.

All colour measurements were made using the 2001 Royal Horticultural Society Colour Chart.
