| Freezer | Not recommended |
About 1–2 weeks at 40°F (4°C) or below, according to USDA FoodKeeper v128. That window runs from the day you bought it — FoodKeeper publishes no separate after-opening figure for this one.
Artichokes, whole is shelf-stable at room temperature: cool, dry pantry, or refrigerate at 40°F (4°C) or below to keep it longer. Refrigerating it mainly preserves quality rather than safety.
Look for: Sliminess or a wet film; Mould or dark mushy spots; Limp, shrivelled, or yellowing leaves; An off or sour smell. Never taste something to test it — when in doubt, throw it out.
USDA FoodKeeper v128 does not recommend freezing Artichokes, whole — it survives but the texture or quality suffers badly.
