I'm totally impressed with how they made it through the winter. I was expecting some paint to peel, or the weathering to start exposing the styrofoam, but they look exactly the same as the day I made them! The plants look good too, I didn't lose any which is saying something.
(Edited to add pics)
This is one established Jovibarba species (hirta?) and a few of my seedlings. Hoping they'll catch up...
