Rozanne is totally hardy in the ground, so winter care is more a function of the pot (material, size) and the temperature than the plant. You might have trouble if the soil in the container freezes. I can't help further since in my climate the temperature rarely goes low enough for overwintering potted plants to be to be of concern.

ok thank you

Since your winter temperatures have the potential to drop down to -10F (and possibly lower), I would not leave the pot out unprotected. Plant roots tend to be the most cold vulnerable portion of a plant and in a container, they are relatively unprotected to ambient air temperatures, which tend to to be far colder than what the roots in the ground would be exposed to, insulated by all that soil mass.

I would either dig a hole in the garden somewhere to heel the planted pot in or store in the garage. As long as it is not exposed to subfreezing temps there.

I put potted Rozanne Cranesbil in a unheated garage...I sat the pot in a wheelbarrow and wrapped a padded chair cushion around the pot...

First bloom: 5-15-24

Looks great.

Wow Jim, that is a gorgeous Rozanne! I have a couple of Cranesbill, but not that one. Do you mind me asking where you bought it? Locally or online? Do you have some secret sauce for getting it to grow so well? [g]

Geranium Rozanne was Perennial Plant of the Year in 2008 and typically forms a smallish mound with a plethora of flowers from June to frost. No 'secret sauce' needed.......it grows like that all by itself :-))

It is also one of the most popular perennial plants sold and is on offer from virtually every online seller as well as most better local nurseries and garden centers.
