here in Atlanta - zone 7 - they are perennial. You can pinch out the
tops until July to make them bushier - and take the pinched out parts
and pot up for more plants.

My friend received a lovely florist mum last spring for a gift and after
it finished blooming, she was going to pitch it. I cut it way back,
potted the cuttings and have about 15 new plants. I know they won't be
the big florist mums but they ought to make something nice. Should be
blooming soon. Plus I planted the "mother" plant and it is full of buds
also...
