Origin & Breeding History: 'Emily Carr' originated from a controlled cross between a rose line which resulted from [(Lammert's selection x 'Morden Cardinette') x 'Morden Cardinette'] and variety 'Cuthbert Grant'. The cross was conducted by the breeder, Dr. Lynn Collicutt, in 1982 at the Agriculture and Agri-Food Canada research station in Morden, Manitoba, Canada. Over a five year period, vegetatively propagated plants of 'Emily Carr' were observed in field and potted culture in different climatic regions and in different Canadian provinces. Evaluations were conducted on the plant growth, resistance to climatic conditions and insects, and reaction to various diseases affecting the leaves. 'Emily Carr' was selected based on its long flowering period, flower form and winter hardiness.

Tests & Trials: The test and trial for 'Emily Carr' was conducted at the Agriculture and Agri-Food Canada research station in Morden, Manitoba during the summer of 2005. The candidate variety had also been evaluated in 1998, 1999, 2000 and 2001. The trial consisted of 3 plants of the candidate variety and 16 plants of the reference variety. The rose plants were spaced 3 feet apart with a 7 foot row spacing. All colour characteristics were determined using the 1986 Royal Horticultural Society (RHS) colour chart and measured characteristics were based on 10 plant measurements.
