Some All-Canadian Roses
by Fred Blakeney, Victoria, B.C.
The Federal Department of Agriculture Experimental Station at Morden, Manitoba, has been carrying on a rose-breeding programme for over 42 years. It is now under the direction of Mr. H. F. Harp, the object in view being to develop a garden rose that will survive the cold winters of the Prairies. Furthermore, it aims to develop winter-hardy roses having the repeat-blooming characteristics, Hybrid-Tea form, fragrance, good plant habit with disease-resistant foliage. This is quite a programme, and one which of necessity must take a number of years to achieve. However, they are well on their way, and have produced the following varieties:
"Prairie Charm", shrub,  introduced in 1959, is a cross between the above-mentioned "Prairie Youth" and "Prairie Wren". It grows to a height of four feet, with light green foliage that is resistant to blackspot. Flowers are semi-double, bright salmon-coral, produced freely, but not recurrent. It is hardy on the Prairies.
