From the 150 Canadian cultivars only 4 are climbing roses. One of these is Langford, a hybrid of R. setigera, developed by Preston from a cross with the polyantha Annchen Müller. Langford needs winter-protection but it has been grown at Ottawa since 1930. It flowers once but produces an abundance of deep rose pink flowers.

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).

"LANGFORD - a climbing rose originated at Ottawa by Miss Isabella Preston from the Michigan wild semi-climbing species rosa Setigera. May never "climb" on the prairies, but blooms while still a small plant. Needs careful protection. Flowers freely produced, valuable, double, nearly red."

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

Langford is the best of the seedlings with double flowers. They are rose color and the small. very full flowers are borne in large clusters. The blooming season starts at the beginning of July and lasts for about five weeks. We use it trained as a pillar as well as on a trellis. It makes an attractive bush also if the canes are winter killed or shortened for any reason.

In "Central Canadian Rose-Breeding," by Isabella Preston: "In 1930 a number of crosses were made using R. setigera as a the female and Polyantha Pompon varieties as male parents...some plants had very double flowers. Of these one was named Langford. This is doing well at the Experimental Station at Morden, Man. The parents were R. setigera x Aennchen Müller. In color the flowers are pomegranate-purple to deep rose-red and they are very double. The blooming period last a month, from early in July to August, and there are quantities of flowers. the shape of the bloom is poor, and it does not set seed."
