The Plant Science Dept. of the Nova Scotia Agriculture College evaluated 58 English Roses to assess their hardiness and disease-resistance. Their results can be found at: http://www.nsac.ns.ca/nsac/ps/annual96/mapple.htm. Constance Spry was found to be winter hardy.
In September 1998, the Montreal Botanical Garden (Le Jardin Botanique de Montreal) carried out a survey of its roses' resistance to black spot, powdery mildew and rust. This is one of the outstanding varieties which showed a 0% to 5% infection rate. The data were taken on well-established roses.
