...ersten Rosenschau im Ostdeutschen Rosengarten Wehrinselpark Forst am 4., 5., 6. Juli ...
...Der Züchter F. Altmüller, Schwerin, hatte die Polyanthaneuheit 1914 'Grete Schreiber' ausgestellt, welcher als Gruppenrose und Topftreibrose mit gedrungenem Wuchs eine gute Zukunft verheißen werden kann.
Ein Sämling derselben Züchters (Altmärker X Druschki) konnte in der Bewertung nicht recht bestehen, besonders da die Blüten gelitten hatten.

..first Rose Show in the East German Rose Garden Wehrinselpark Forst on 4., 5., 6. July...
...The breeder F. Altmüller of Schwerin had exhibited the polyantha novelty 1914 'Grete Schreiber', to which a good future can be promised as group rose or forcing rose for containers.
A seedling of the same breeder (Altmärker X Druschki) could not quite succeed in the rating, as especially its blooms had suffered.
