Some All-Canadian Roses
by Fred Blakeney, Victoria, B.C.
Now we come to the Dean of Canadian Hybridizers in the person of Dr. Frank L. Skinner of Dropmore, Manitoba, who has been hybridizing roses and other plants for over sixty years. His first recorded origination was a cross between R. acicularis, an extremely hardy species rose found probably nearer the Arctic Circle than any other rose, and R. spinosissima, another very hardy species. This was introduced in 1925 and named "Larry Burnett". It has large (3½ inches in diameter), semi-double, cupped, very fragrant, blush-white blooms, with the centre being deeper. The plant is bushy and vigorous, a profuse bloomer, and is very hardy.
