The Atlantic Giant Pumpkin is a Legendary plant tied to the Fall Harvest Event in Grow a Garden 2. It sells its produce for Leaves instead of Sheckles, carries a special growth ability, and ranks among the highest-value crops available during the event.
Quick answer: Load into the Fall Harvest map by talking to Ethan the Explorer at the center of the main map, farm 600,000 Leaves, then buy the Atlantic Giant Pumpkin seed from the Fall Harvest Seed Shop when it restocks (2% chance). It can also be purchased for 379 Robux.

How to get the Atlantic Giant Pumpkin
Tip: Because the restock is rare, keep a Leaf buffer on hand so you can buy the moment it appears rather than losing the window.
How the growth ability works
The Atlantic Giant Pumpkin is one of the few plants in the game with a built-in ability. It is immune to every Mutation and to watering effects, and it can keep growing in size with no upper limit. You can leave it untouched on your farm and let it swell for the length of the event.
Growth is not linear. The larger the pumpkin gets, the slower it grows, so its size gradually plateaus rather than climbing forever at the same rate. The immunity to Mutations also means Mutation-based value boosts do not apply to it.
Crop value and harvest behavior
Each crop sells for an average of 300,000 Leaves, with a price-floor value of 270,750 Leaves at lower weights. That return, paired with the free-growing ability, makes it one of the strongest earners on the Fall Harvest map.
Unlike other Pumpkin-type plants, this one is Multi-Harvest. You can sell its yield repeatedly without destroying the plant, so a single Atlantic Giant Pumpkin keeps producing after each harvest.
| Detail | Value |

| Minimum weight | 5.25 kg |

| Prime duration | 30 minutes |
| Decay period | 2 days 2 hours |
| Full decay duration | 2 days 2 hours 30 minutes |
Event window and availability
The Fall Harvest Event runs until September 30, 2026. The Atlantic Giant Pumpkin is only available through the event’s Seed Shop while that window is open. It is not confirmed whether crops and items farmed during the event will stay usable once it ends, so plan your Leaf spending before the deadline.
Because the seed restock is so infrequent, the biggest risk is running out of time rather than running out of Leaves. If you want the pumpkin’s full size potential, plant it early so it has the longest possible stretch to grow before the event closes.
