Frau Karl Drüschki (Hybrid Perpetual) [Mme Caroline Testout x Merveille de Lyon] (SJH)

The Garden, May 4, 1907

An American catalogue said, "Its only fault is an overexuberant growth for a small space. It requires hard-hearted pruning to keep it of manageable size." Druschki and the other vigorous Hybrid Perpetuals are not "over-exuberant" in Europe, not solely because they are budded from flowering wood, which in itself has a tendency to moderate the growth, but mostly because they are budded on a rootstock, R. canina, which, not being overvigorous, checks the exuberant tendency. This practice is the counterpart of that in which special rootstocks are used to produce dwarf fruit trees. A pear variety, for instance, that grafted on quince will always remain a bush, may grow into a large tree when grafted on some other rootstock.
     Lambert says it is a grave error to bud Hybrid Perpetuals on Multiflora, which forces an extraordinary wood growth at the expense of bloom. As Hybrid Perpetuals are coming back into use in Germany he is now experimenting with various rootstocks to dwarf the Hybrid Perpetuals on the same principle as dwarfing fruits. I wonder what kind of Druschki plants would grow if budded on R. rouletti, which experiment I am going to do this summer.

Gardeners' Chronicle, p. 421 (December 4, 1902)
A GOOD white hybrid perpetual is a gain long desired by rosarians. That it has been obtained may be judged from our experience here as well as from the following account which we condense from the November number of the Rosen Zeitung:—
     "This Rose affords another example of the fact that the value of a new hybrid cannot be fairly estimated in the first or second year of its existence. The present Rose is a seedling from Merveille de Lyon, the female parent, Madame Caroline Testout having been the pollen parent. It has been in the raiser's garden at Treves since 1898. In that year no flowers were produced, but in 1899 there appeared on those branches that had been left unpruned and unprotected in the winter four or five white blooms of good shape. More flowers came to perfection in the autumn, and the work of propagation then began.
     In 1900 the Rose was shown at the Rose Exhibition held at Treves, but it obtained no prize. Since then it has been exhibited at Treves, Coburg, Dusseldorf, Frankfort-on-Main, and Mayence, and it has made successful appearances in England, Holland, and France.
     The plant grows freely both in height and width, and is robust in habit. The older bushes produce shoots of from 6 to 9 feet in length, hence it can be used as a bush, or trained as a standard or pyramid. A distance of not less than 5 feet should be allowed between the plants. The buds are very long and pointed in shape, the flowers are snow-white, without any shade of rose or cream. The colour is even purer than that of a Niphetos. The flowers, when cut in bud, last in water for a week.
     The flowering season continues from that of the earliest of the Tea Roses till frost sets in. One-year-old shoots bloom for the most part only at the tip, therefore free pruning is advisable. The stem is stiff, like that of any other hybrid Rose.
     The hybrid is named after the wife of the President of the German Society of Rosarians.
     Our illustration (fig. 143) is taken from a phot graph obligingly put at our disposal by the Rev. F. Page Roberts, who thinks very highly of the new comer.
