I’ve built on the big snowy lot, and it’s possible to make areas with columns and roofing where you can see the bare ground underneath. Everywhere else is constantly covered with snow. But I didn’t test if this area is actually sheltered enough to grow plants. I’m guessing yes, because of the roof. But I don’t know if that means the CoL plant patches will work there. Trying those on a snowy area seems like it would be frustrating because you can’t see anything low to the ground in those parts.
I had also built a deck with a pool, all covered by a roof. But in freezing temps, I realized that pool wasn’t actually protected because most swim options were grayed out. But I am under the impression that this is even an issue with indoor pools.
