Die Schnittblumenschau.
[Emil Chasté in Wilmersdorf] hatte Blumen der Böhmschen Rank-rose 'Graf Zeppelin', der Immerblühenden 'Crimson Rambler', der Polyantha-Neuheiten 'Erna Teschendorff' und 'Mme Taft', der Kieseschen 'Deutschland' und einer 'Weissen Mme. Caroline Testout' von S. A. Vosters & Söhne in Riel (Holland) ausgestellt, die freilich unterwegs sehr gelitten hatte.

The Cut Flower Show.
[Emil Chasté in Wilmersdorf] displayed flowers from Böhm's climbing rose 'Graf Zeppelin', the always flowering 'Crimson Rambler', the polyantha novelties 'Erna Teschendorff' and 'Mme Taft', Kiese's 'Deutschland' and a 'Weisse Mme. Caroline Testout' from S. A. Vosters & Söhne in Riel (Holland), which admittedly suffered greatly on the way.

Rosen.
Weiße Caroline Testout ist eine der wertvollsten Neuheiten unserer Zeit. Die Firma S. A. Vosters & Söhne, Riel (Holland) erzielte sie durch Kreuzung von Caroline Testout mit Kaiserin Auguste Viktoria. Wuchs und Blumen gleichen in Bauart der alten Caroline Testout, so daß man namentlich im entlaubten Zustande keinen Unterschied finden kann. Durch ihre Reichblütigkeit und Haltbarkeit ist die Weiße Caroline Testout aber von ganz besonderem Werte für Blumenliebhaber und Schnittrosenzüchter; nach England und Amerika verschickt, trafen die Blumen in gänzlich frischem Zustande ein.

Roses.
Weiße Caroline Testout is one of the most valuable novelties of our time. The firm, S. A. Vosters & Sohne, of Riel (Holland), obtained this rose by crossing Caroline Testout with Kaiserin Auguste Viktoria.The growth and blooms are very like those of Caroline Testout, so that no differences are noticeable, especially when the foliage is removed. Thanks to its floriferous and vigorous nature, Weiße Caroline Testout is especially valuable to flower lovers and growers of cut roses for the trade; when sent to England and America, the flowers arrived in completely fresh condition.
