Wyrmvine

The Wyrmvine sits at Prismatic rarity, the very top of the Grow a Garden tier ladder, which immediately tells you everything about its economics: this is not a seed you casually buy from the rotating shop. Prismatic crops are gated behind events, crafting, or rare luck, so the real "cost" is the grind to obtain it rather than a listed Sheckle price. Because its exact seed cost and sell price are not recorded here, treat its value as event-driven and scarcity-priced rather than something you can math out against a simple buy figure.

What makes Wyrmvine genuinely interesting is its stacked typing: it is flagged as Night, Toxic, Stalky, and Spooky all at once. That quadruple tag is rare and it means an unusually wide set of type-targeted pets, sprinklers and event items will buff it, so a single well-mutated Wyrmvine can soak up bonuses meant for four different crop categories.

For mutation stacking, lean into multiplicative weather and event mutations rather than flat additive ones, since a Prismatic base value scales hardest with high multipliers. Grow Wyrmvine in the late game, once you already run reliable sprinkler coverage and a mutation-friendly pet roster; early on you lack the infrastructure to convert its potential into real Sheckle returns.
