This is a list of sites that I find useful when searching for plant information, sales, solutions for problems, garden design and just random stuff. The opinions are mine. If you don’t agree, oh well. That’s OK.

This is never a complete list. I’ll be adding to it as I find new or rediscover interesting sites. Hope you find something useful.
