Fall Fruits and Vegetables
What's in Season in Fall?
Look for these fall fruits and vegetables at farmers markets and in produce departments for the best flavor (and greatest value) in season.
Apples are one of those fruits people have forgotten have a season. But they do, and in the Northern Hemisphere they're harvested late summer through fall.
Artichokes produce a second, smaller crop in the fall (the first go-around is in the spring) that tends to produce small to medium artichokes.
Arugula is a cool weather peppery green harvested at different times in different places (winter in warm climates, summer in cool ones) but grows in many places during autumn.
Beets are in season in temperate climates fall through spring, and available from storage most of the year everywhere else. Fresh beets are often sold with their greens still attached.
Belgian Endive are mostly "forced" to grow in artificial conditions. Their traditional season (when grown in fields and covered with sand to keep out the light), like that of all chicories, is late fall and winter.
Broccoli can be grown year-round in temperate climates so we've forgotten it even has a season. It is more sweet, less bitter and sharp when harvested in the cooler temperatures of fall in most climates..........
