Potato

The Potato in Grow a Garden is far from the humble vegetable its name suggests: it is a multi-harvest Mythical crop introduced in the Fairy Event. That Mythical grade pushes its base sell value high above ordinary garden staples, and the multi-harvest trait turns one planting into a repeating payout, so the long-run yield per seed easily beats one-shot crops of the same rarity.

Its Vegetable and Root typing is comparatively narrow, which shapes how you should mutate it. Fewer type-targeted boosters and pets hook onto Root crops, so the reliable value comes from broad mutations rather than niche type bonuses — chase weather effects and the high-multiplier Gold and Rainbow rolls, and let each successive harvest reroll the chance at them.

Because it is a Fairy Event crop, the seed is not freely restocked, so its scarcity gradually firms up the price over time. In progression terms, slot the Potato into the mid-to-late game once you have mutation gear running: park the plant, leave it producing across many harvests, and only cash out the copies that land a strong mutation stack while keeping the base alive.
