Here are in reverse chronological order sorted images of the habitats in the USA. For a better overview, the galleries can also be filtered by individual species or states.
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 articles have been published elsewhere, too.
