Check out the Cacti/Tender Succulent Forum and of course don't forget to come see us at the Sempervivum Forum and The Sedum Forum. Lots of interesting ideas in the Container Forum also.
Thank you for giving Christine that link Karen.
I'm sure you will be finding all kinds of Forums to start 'Watching'. Oh, before I forget, Boopaints (Becky) has an amazing Forum for Garden Art.
Okay, I have to stop now, because the entire site is full of most amazing things. Have fun discovering your favorite places.
