Furthermore, experiments have reached a dead point because the caladium seguinum grows only in North America and during the war cannot be imported in adequate quantities. Dr. Koch’s attempts to grow this plant from seed cultivated in hothouses have been successful, it is true; but the process is very slow and the yield is not sufficient to permit carrying on experiments on a large scale.
Dr. Koch is hopeful that this will be remedied if it is possible for us to obtain permission for him to build a larger hothouse. I promised him this.
For the time being this is the first and only practical step to promote the project.
I shall continue reports periodically.
Heil Hitler!
