More information
The majority of the most winter-hardy roses suited to severe Canadian winters were developed by Agriculture Canada. Marie Bugnet is an exception; like Therese Bugnet, it was bred by the Alberta rose grower George Bunye. The flowers are pure white, densely petalled, with wavy, paper-textured petals, borne in small clusters (usually 3–5). They are easily damaged by rain and do not set hips, while the buds and shining white blooms are characteristic. The shrub is atypically compact for a rugosa. Long, disease-resistant, light green, wrinkled leaves cover the plant, and the foliage shows distinct autumn coloration. In winter, the prickly shoots become a dense reddish-brown. It begins flowering early and continues until the first frost. On its own roots it produces many suckers and can form a thicket.
