Well, cabbages, broccoli, cauliflower, collard greens, mustard greens, kale, brussel sprouts....all of those taste even better grown in cold weather. .
Garlic. Separate a head into cloves carefully, not nicking them, and leaving on the skin. Plant the larger cloves, point up, about an inch deep, unless it's been raining, or is about to, then go deeper, so they don't float. Each clove will give you a head next summer.
I'm timing mine to mature around the middle of Oct. Just check the seed packets for days to maturity. The brussels, broccoli and cauliflower do best in cool weather (hottest days below 70) They are actually sweeter if they get a couple of light frosts on them.
