Grow a Garden Mutation Multipliers
Mutations in Grow a Garden multiply a crop's sell value. This page collects the key multiplier values, how each tier triggers, and how stacking actually computes.
How the math works
Crops have a base 1% chance to mutate at harvest. Gold and Rainbow seeds guarantee one, and pets like the Unicorn or Golden Dragonfly passively raise the odds. High-tier mutations only trigger during specific weather and admin events.

Frequently asked questions
What is the highest mutation multiplier?
Abyssal at 240x - a combination mutation built from Eclipsed plus Voidtouched.
Do mutations stack?
Yes, up to five per crop, and they multiply each other - that is how billion-Sheckle harvests happen.
How do I force mutations?
Gold/Rainbow seeds guarantee one per crop; beyond that, pets, sprinklers, weather events and admin events drive specific mutations.
