When I read the name, I recognized it! I had purchased salvia plants from him years ago through his World of Salvia online site. I had no idea about his mental issues. He was truly brilliant when it came to his knowledge of salvia cultivars. He was the Salvia Guru at that time.
Richard's life story actually reminds me of my uncle, who lived a similar lifestyle. (But his brilliance was in restoring antique motorcycles.) Similar sad story because of some state of mental illness.
