I have some that also need to go. Then I saw something about painting them. I'm going to give that a try this fall and hope for the best.

Where are you located? How cold does it typically get in winter? Glazed ceramic pots, typically Vietnamese in origin, are often considered to be "frost proof" and will withstand below freezing temperatures well but there is a limit :-))

I have a large collection of frost proof glazed ceramic containers that have withstood many winters unimpaired, including a few dips down into the low teens. But they are not inexpensive and they are also heavy - and very heavy once filled :-))

Today's resin and fiberglass containers are much more stylish and up-to-date looking than the standard (cheap) round, plastic flowerpot shapes found at common outlets like HD, Lowes or Walmart - see link. But they are also not inexpensive but are pretty much impervious to any cold damage.

Hah, maybe I'll try the painting because the shape is actually fine.

Temperatures will dip into single digits.

I recommend looking at Fibercrete and GFRC-concrete planters. They patina them to look like stone and are a lot more durable than plain old concrete. They are supposed to be able to take freezes well too.
