I just took delivery of the Little Free Library I've posted about in the Seeds forum -- our model also has a Seed Exchange drawer and part of what they sent us was a selection of seeds. Coincidentally, one packet was of Riesentraube -- the picture looks like red cherry tomatoes.
Sadly all the seeds they sent are vegetable seeds and this is not the time to start cucumbers and tomatoes in this part of the world but, seeds will keep. Anyway, interesting, Rick, that you should run into that cultivar info just now.
