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.
H. V. Machin. Hybrid Tea. (A. Dickson & Sons, 1914.) Massive crimson buds and intensely red, very large flowers of perfect shape, with a tight pointed center; fragrant. Plant robustly erect, bearing its heavy blooms on stout stems. Excellent bloomer in spring.
Close to the Hybrid Perpetuals in habit and dearth of summer bloom. Blues badly but splendid in spite of it. Dr. Van Fleet admired this Rose and said: “Forgive it for sparse blooming; when it does bloom it makes up for it in beauty."
