In Grow a Garden (Roblox), mutations will increase the value of your crops by a standard multiplier.
They also alter the appearance of your crops, including color, texture, glow, particles, and more.
Mutations are triggered by weather events, the use of tools, or the planting of special seeds.
Most mutations can be obtained automatically when the crop is growing or fully grown.
