As you probably guessed from the theme name, this free WordPress theme has green and (mostly) brown colors. It is designed by FreeCSS.info and ported into WordPress by me. The sidebar is widget-ready, and the theme has native tag and Gravatar support (WordPress 2.5 and above only).
Tags: brown, FreeCSS, green, right sidebar, two columns
Very nice theme, is it widget-ready?
Yep, widget-ready and Gravatar-ready.
