Selection of 'Monomb' was based on its large size, and open, rounded and mounding growth habit.
Tests & Trials: Trials for 'Monomb' were conducted in a polyhouse during the summer of 2007 in St. Thomas, Ontario. The trial included a total of 10 plants each of the candidate and reference varieties. All plants were grown in 7.5 litre containers during the summer of 2007. Observations and measurements were taken from 2 year old plants, 10 plants of each variety, on July 18, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
