Are there any flowers I could plant now (3 October) that would survive
and look moderately pretty in a few months?

I live near Atlanta. The flowers would be in a big pot that would be
in a screened-in porch on the south side of the house. They'd have at
least a few hours of sun each day. Temps will occasionally get below
freezing in December and January, so I could bring them inside on those
days, if necessary.

Thanks for any info,

Mel
