Thank you Cinta, Iris reticulata will grow down to zone 3 and would look great in your garden and containers. It produces new bulbs very fast, so it wouldn't be long before you would have them transplanted everywhere.
Cameron the S. monregalense grows like a weed, tough and reseeds easily. Trollii, I just realized from looking in our database, is not a sedum but a Rhodiola saxifragoides.
Rhodiola saxifragoides
I need to print a new label for this one.
Bev, you can grow Rhodiola saxifragoides easily, it is hardy to zone 6.
It will make it through colder winters than we ever get here in the Willamette Valley.
