I first created this site back in 1998 to document the wild plants that I encountered.  But it has grown into a clearinghouse of information on landscaping, backyard birds, butterfly gardening, plant identification and making paper from plant fiber. After leaving Kansas, I thought of deleting the site. But realize it has a wealth of information that people rely upon.

Hosting the site is involved. I’d like to thank those who have donated to help defray the web site hosting fees.  If you would like to contribute, please click the Donate button. Thank you.
