What planter material holds up best outdoors in freezing climates?

Reviewer consensus

Reviewers consistently flag terracotta and unglazed clay as vulnerable to freeze/thaw micro-cracking when wet, with high-trust r/gardening commenters specifically calling this out for wet climates like the PNW. Resin, polypropylene, and resin-stone composite planters are repeatedly cited as the more freeze-tolerant choices because they resist cracking and UV fading, though painted finishes on some composite pots reportedly don't survive frost as well as molded-in color.
