Is heaving a big issue with Heuchera in general, or with all plants? I've never seen it here before. The ground here stays pretty frozen during the winter, so maybe that is why? These plants should be in the ground a good amount of time before it freezes, so maybe that will help? I really have no idea what to expect! I've planted several other Heuchera in the fall, and have never lost one. Either way, I'll keep an eye on them, and push them back in the ground if needed. This will give me something to do during the winter! I can watch my plants trying to crawl out of the ground and head south for the season!
