The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from a single rooted cutting transplanted into a 20 cm standard pot on June 23, 2011. Observations and measurements were taken from 10 plants of each variety on September 29, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
