I was a planting guide from our cooperative extension in Whitevill , NC.
Let me check potato:
Plant Feb 5 to March 22.

I have planted a few 2 weeks ago and found few in the kitchen that have sprout. I will plant them this Friday. The guy in the extension office told me ( 2 weeks ago ) "if you plant them now you can harvest in April. But I found it to generalized. Potatoes like tomatoes have different maturity. In general it take 85 days to 110 days, depending on the variety.
Potatoes shut down when the sol temperature get to 75F and higher. I think down here we can also do fall planting.
