Turnip

The Turnip is a common, multi-harvest crop from the limited Fall Market Event, and that combination defines its economics. Common crops sit at the bottom of the value ladder, so the Turnip will never post big per-unit sell prices — but the multi-harvest trait quietly rescues its worth. Instead of a one-and-done payout, a single plant keeps yielding across many cycles, so the modest base value compounds into a steady trickle that easily out-earns its low seed cost over time.

The catch is its limited Fall Market origin: it is not a permanent shop seed, so its real cost is event participation, and once the event closes you cannot simply rebuy it. Its typing as a Fall, Root and Vegetable crop means seasonal Fall boosts plus root- and vegetable-targeted pets all apply, which is exactly how you squeeze extra value out of an otherwise humble common.

Grow the Turnip in the early-to-mid game as reliable background income — plant it, let the multi-harvest run, and let category bonuses pad the margins. For mutations, even a cheap Gold roll noticeably lifts a common's payout, so it is worth chasing on a long-lived plant like this.
