Here you can find my publications about American Rhododendrons. I recommend becoming a member of the Deutsche Rhododendrongesellschaft, not just to read my contributions but also those of other authors much earlier than here. The 120-130 pages booklet is published twice a year, is well designed and contains lots of color pictures. Some of my publications have been published elsewhere, too.
