I like to use semps and sedum in my containers. This one also has some echeveria. It is not hardy in my zone, but I dig up in the fall and replant in spring.

More Sedum and Semps

Plantman - Very cool pots and I really like your plantings. What did you use for molds? Do you use the standard hypertufa recipe? Very nice!

The top one was your basic hypertufa recipe. I think I used a plastic bowl and applied the mix on the outside of the bowl - not real creative.
The other container was actually the start of a tufa ball. So it is mostly portland and sand, maybe a little peat. I used fiber drywall tape, and started to cover a round inflatable ball with the intent of covering the entire ball. I never finished and decided to use it as a container.
thanks - Mike

As you can see, I love to plant sedums and herbs in my tufa containers.
