Hypertufa plant containers are so cute!
I've made lots of concrete plant containers and have heard of hypertufa, but have not yet made any. The great feature of hypertufa is less weight than concrete. I love my concrete containers, but huge containers are almost impossible to move around.
Fine Gardening (photo source) has an excellent article on hypertufa, including Peg's secrets, whose containers are shown in the photo.
