Plumwillow

The Plumwillow is an exclusive Mythical crop, and that single fact dictates its entire economic story. Exclusive seeds never sit in the rotating shop for plain Sheckles, so the real "cost" is event grinding, trading, or robux-tier purchases rather than a listed seed price. That investment only pays back if you treat the plant as a long-term asset, not a quick flip.

Its triple classification as a Woody, Sweet and Fruit type is the key to squeezing value out of it. Woody and Fruit tags mean it responds to the widest pool of type-targeted boosters and weather mutations, and a Sweet-tagged fruit is exactly the kind of crop where stacked mutations multiply hard. Aim to layer environmental mutations (Wet, Chilled, Frozen) on top of high-value ones like Rainbow or Gold before you ever sell.

Because exclusivity caps supply, a single heavily-mutated Plumwillow can out-earn dozens of common harvests. Grow it in mid-to-late progression, once you own mutation-boosting gear and weather sprinklers, so each harvest lands at maximum multiplier. Selling it raw early is the one genuine mistake here.
