Can I individually plant them in pots and keep them in the house over winter or do they need to go dormant? Can I plant these small plants in MN and have them come back next spring? I'm assuming that this far north they need to be mature plants to reseed themselves. This is the first time I have had hollyhocks and any advice would be helpful. Thanks.

Can you grow double hollyhocks in big containers?
