Single Roses.
In our Nurseries there are no more attractive objects than the Irish single varieties, and they are so marvellously free flowering that it is impossible to say too much in their praise. During the entire growing season they are virtually always in bloom, and their lasting properties are most surprising.
Morgenrot... P. Lambert, 1903, vigorous. Bright crimson, with large white centre; very free and perpetual; very fine.
