Beautiful Paul!
I've never seen anything like them. That would be the only way I could have cactus in my yard year round here in KY. Now if only I were a metal sculptor ~ or knew one.
Name: Paul Utah (Zone 5b) Grandchildren are my greatest joy.
I think they would be beautiful in a bed of rocks or gravel in a xeric landscape. You can see on the right of the Saguaro some with glass blossoms. I didn't care for those.
