Hi Teresa.
There are so many different sedum with different growing requirements (growing zones). The best way to decide which you would like to have is using our database, it gives all the information about each plant, including growing zone.

Do you want ground cover types, or tall/upright succulents, or both?
Let the adventure begin. Just let us know if you have questions about particular ones that you like.
