Both heuffs and semps do equally well in pots or ground. I've never heard of cil-dri. Oops, just read your last post. That definitely will not work. John Deere Landscaping carries Turface.
I do both pots and inground.
I am finding that the Turface holds to much water for our PNW wet season. I will have to rethink how much Turface I use. (Rethinking this again, seems the Turface allows air circulation and does not compact, so should still work here in PNW)
Would love to have you add pictures of your plants to our databases. We are adding dates pictures where taken so we can track each Cultivar as to changes in the seasons. Some go through really big changes in size, shape and color from one season to the next. Let me know if I can help with anything else.
