Everblooming Roses
The so-called Everblooming Roses include the Hybrid Tea and Pernetiana groups. They do not bloom all the time, but if kept healthy and growing steadily, one crop of flowers succeeds another at brief intervals.
Burgemeester Sandberg. Hybrid Tea. (G. A. Van Rossem, 1919.) Globular buds, opening to large, cupped blooms of silver-pink, heavily shaded coral- rose; very double and slightly fragrant. Growth strong and bushy; foliage large; remarkably free blooming for such a large-flowered variety.
Beautiful both in bud and open flower. Ought to become very popular for cutting and bedding when better known. Each year we are more impressed by its merit. It is a much better Rose than we expected at first.
