Description:

'Emily Carr' is a large shrub rose variety with an upright to bushy growth habit. The young shoots have moderate to strong, purple anthocyanin colouration.

The upper side of the leaf is dark green with weak to moderate glossiness. There are seven leaflets per leaf. The terminal leaflets have a round shaped base and serrate margin.

'Emily Carr' begins flowering mid-season and flowers almost continuously for more than ten (10) weeks. There are a moderate number of flowers per flowering shoot and the flower pedicel has a moderate to numerous amount of prickles and few hairs. The flower bud is pointed in longitudinal section and the sepal extensions are moderate. 'Emily Carr' has semi-double type flowers which are dark red aging to red. They have an absent to very weak fragrance. When viewed from above, the fully opened flower is round in shape. When viewed from the side, it is flat on the upper part and flattened convex on the lower part. The petals have a medium sized, purple red spot at the base on the outer side and a large, purple red spot at the base on the inner side. The margin of the petals is weakly reflexed with weak to moderate undulation. The outer stamen filaments are white with a green tinge. The style is medium to long, yellow green and has dense pubescence. The stigma is positioned slightly below the level of the anthers. The receptacle is small and pitcher shaped in cross-section with no prickles on the outer surface. 'Emily Carr' is resistant to powdery mildew and susceptible to black spot.

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.
