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 Dawn", shrub, also introduced in 1959, is aresult of crossing "Prairie Youth", "Ross Rambler", "Dr. W. Van Fleet" and R. spinosissima altaica. This one grows to a height of 5 feet and is of upright habit. The foliage is dark green and glossy, while the flowers are 2 to 2½ inches in diameter, of a double, glowing pink with no trace of magenta or fading. It blooms from early July, and intermittently throughout the summer on the current season's wood, and it is hardy on the Prairies.
