Princess Thorn

The Princess Thorn is a limited, multi-harvest Divine crop from the Beanstalk Event, and that combination is what makes it economically special. Divine sits at the top of the rarity ladder, so its base sell value is already among the highest in the game, but the multi-harvest trait is the real money-maker: instead of being uprooted after one pick, it regrows and lets you collect repeatedly from a single planting. That turns one seed into an ongoing revenue stream and dramatically improves return on the plot it occupies.

Its typing as a Prickly and Leafy crop means it benefits from any tool, pet or buff aimed at prickly or leafy plants, giving you two synergy lanes to exploit rather than one. For mutations, the math favors anything multiplicative: apply Gold or Rainbow and let it persist across every regrowth, because the bonus is effectively re-earned on each harvest cycle of a Divine base.

Since it is event-limited, secure it while available and treat it as a long-term anchor crop. A multi-harvest Divine is a late-game asset you keep producing from, not a one-time sale.
