Origin & Breeding History: 'CA29' arose from the cross 'My Hero' by 'Frontenac' conducted at the Agriculture and Agri-Food Canada Morden Research Station, Morden, Manitoba in 2001. Selection criteria included hardiness, flower colour and disease tolerance.
Tests & Trials: Trials for 'CA29' were conducted in plots at the Prairie Shade Nursery, Portage la Prairie, Manitoba during the summer of 2011. The trial included a total of 10 plants each of the candidate and reference varieties spaced 2 metres apart between rows and 0.6 metres apart in rows. All plants were grown from 2 year old plants previously grown in 2 gallon pots. Observations and measurements were taken from 10 plants of each variety. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
