真的不多（Mississauga 、瀑布那边的除外，我说的是大多数华人住的401以北地区），就我自己种过的来说，可以抵抗零下三十度的只有John Cabot，Camp fire, Canadian Shield, Kashmire 这几种 zone 3到zone4的，Knockout也还行。其它的DA玫瑰啥确实是好，但能不能熬过冬天，只能看天意。
Hardy Canadian Shrub / Climber (Dr. Felicitas Svejda, Canada, 1969) Double, rosy pink, fragrant flowers bloom freely in mid-season with fall repeat. Climbs 8 to 12 feet or can be grown as a shrub. Glossy, medium green, disease-resistant foliage. An excellent climber for cold regions.This rose in the Canadian Explorer series is named after Italian explorer and adventurer John Cabot (c. 1450 – c. 1499). Cabot is credited with the 1497 discovery of parts of North America under the commission of Henry VII of England. The official position of the Canadian and United Kingdom governments is that he landed on the island of Newfoundland.
