How long do you keep seed? I always thought fresh seed was best and never
stored for more than a year. I'd appreciate advice - usually I just buy
fresh every year but it goes against the grain to be extravagant!

From an old 4H flier:

LONGEVITY OF VEGETABLE SEED

1 YEAR
onion
parsnips

2YEARS
sweet corn

3 YEARS
beans
carrots
peas

4 YEARS
beets
cabbage
pumpkins
squash

5 OR MORE
cress
cucumbers
lettuce
radishes
tomatoes
turnips

(I assume vegetables not listed would fall into the range of close relatives;
spinach and chard would lump with the beets and peppers and eggplants
with the tomatoes.)
