Some All-Canadian Roses
by Fred Blakeney, Victoria, B.C.
The Central Experimental Farm at Ottawa, as may be expected, has done considerable rose breeding over a number of years. Dr. William Saunders started this programme with "Grace", a hybrid rugosa, in 1892, followed by "Agnes", also a hybrid rugosa, in 1900. After the passing of Dr. Saunders, the rose breeding programme was taken up by Miss Isabella Preston, and she produced nineteen hybrid species. Nearly all are shrub roses with one burst of bloom in June, but there are three climbers: "Agassiz" (1930), "Langford" (1930), and "Patricia Macoun" (1923).

Patricia Macoun - 14

Correspondence: Dr. F. L. Skinner to H. M Eddie.

I have a few seedlings of Rose Patricia Macoun that are less than a foot high here, are continous flowering, quite double and nicely fragrant. I have had these with forty flowers out at one time on one panicle. Enclosed is a photograph of a small pot grown plant..."

In "Progress in Breeding Hardy Roses," Isabella Preston says,

Another rose species with a climbing habit of growth that we grow is R. helenae. Although it winter kills almost to the snow line, it flowers and sets seeds profusely. From some open pollinated seeds a plant with double, white fragrant flowers was obtained. This is a very vigorous plant when grown and treated like the other climbers in our collection so it was named R. Helenae var. Patricia Macoun in honor of Dr. Macoun's daughter. The blooms are not quite two inches across and open out flat to show the golden yellow stamens. There are as many as thirty buds in a cluster and when in bloom, the plant is a wonderful sight. We grow it trained as a pillar as well as against a trellis. It commences to bloom in the middle of June lasts for about three weeks.

In "Central Canadian Rose-Breeding," Isabella Preston says,

An open-pollinated seedling of R. Helenae has been named Patricia (R.23.19.02) The flowers are double, but open so that the yellow stamens show. They are fragrant and produced in large clusters. The plants seem to winter better than most climbing roses when given the same protection. In districts where climbing roses do not have to be covered for winter it should make a good variety for covering pergolas and arches.
