Zonal geraniums were a favorite of my Grandmother. I wish I could ask her because I don't know. Anybody have experience with them coming back from the roots?

Yes! Even in north Central Texas. They aren't long lived perennials but they do come back when we have mildish winters.

Thanks! I think I will just let it rest for a few more weeks and see what happens. I've been watering the pots, maybe they'll make it!

Tops generally die back if there is much direct frost exposure. When we see a few come through in my part of USDA 8 it is when they are located in spots like south facing planters underneath building overhangs. And the previous winter was a mild one.
