Yarrow

Yarrow is a Divine-tier crop introduced during the Smithing Event, and that origin shapes its entire economics. Event-locked Divine crops do not sit in the everyday seed shop, so there is no fixed Sheckle buy price to weigh against returns — the cost is your event participation and crafting effort. Because the exact seed cost, sell price and growth time are not logged in this entry, judge Yarrow as a prestige payoff for clearing the Smithing content rather than a farmable income loop.

Its key mechanical hook is that Yarrow counts as a Flower type crop, so every Flower-targeted pet, sprinkler and buff item in your kit applies to it. Flower synergy is one of the more developed type ecosystems in the game, which gives Yarrow strong upside if you have already invested in Flower-boosting pets.

On mutations, a Divine base value rewards high multiplicative stacks — chase weather and rainbow-style mutations over small flat bonuses, since they scale a Divine crop far harder than a common one. Grow Yarrow in the mid-to-late game, when you can pair it with Flower-type infrastructure and protect its harvest with mutation coverage; treating it as a one-off event trophy early simply wastes its multiplier ceiling.
