Storage life of vegetable seed varies significantly between vegetable species. Storage conditions also affect the length of time seeds remain viable. In general, store vegetable seed in a refrigerator in an air tight container such as a quart jar. Placing a moisture absorbing silica packet in the jar is also beneficial.

The following vegetables are listed with their general storage life under ideal conditions:
5 years or more: beets, broccoli, Brussels sprouts, cauliflower, cabbage, collards, kohlrabi, chicory, escarole, radicchio, cucumber, kale, lettuce, melons, mustard, peppers, radish, rutabaga, sunflower, tomato, and turnip.

3+ years: beans, carrot, celery, chard, eggplant, parsley, peas, pumpkin, salsify, and squash.

1-2 years: corn, leek, onion, parsnip, and spinach.
