Mutations are weather-triggered special effects that add a multiplier to your plants' value. They stack additively with each other and with the Lush variant, making high-mutation Lush plants the most valuable things in the game. This guide covers every confirmed mutation, how stacking works, and the best combos to chase.
How Mutations Work
When a weather event occurs, any plant on your plot that was planted during that weather event (or sometimes exposed to it) can receive a mutation. Mutations are additive: each mutation adds its multiplier to the plant's base multiplier pool.

All Confirmed Mutations
| Mutation | Multiplier | Trigger | Rarity |
|---|---|---|---|
| ๐ซ๏ธ Foggy | 1.5ร | Fog weather | Common |
| ๐ Flooded | 1.5ร | Rain weather | Common |
| ๐ง Soaked | 1.5ร | Rain weather | Common |
| ๐ง Chilled | 1.5ร | Snow weather | Common |
| โ๏ธ Snowy | 2ร | Snow weather | Uncommon |
| โญ Starstruck | 6.5ร | Starfall event | Very Rare |
| โก Shocked | 4.5ร | Thunderstorm event | Rare |
| Sandy / Mossy / Muddy | TBA | TBA | TBA |
Rain weather gives two common mutations (Flooded + Soaked), meaning plants planted in Rain can receive both for a combined 1.5 + 1.5 = 3ร bonus. Snow similarly offers Chilled + Snowy for 1.5 + 2 = 3.5ร.
Additive Stacking โ The Formula
The stacking formula in Garden Horizons is additive across all mutations a plant has. The final value multiplier is calculated as:
Final Value Formula
Base Price ร Variant Multiplier ร (1 + ฮฃ Mutation Multipliers)
Note: exact formula may be refined as more data is confirmed
Example: Lush Beetroot with Starstruck + Shocked
| Component | Value |
|---|---|
| Base price | 3,750 ๐ฐ |
| Lush variant (3ร) | ร 3 |
| Starstruck mutation | + 6.5 |
| Shocked mutation | + 4.5 |
| Total multiplier | 1 + 6.5 + 4.5 = 12ร |
| Estimated sell value | 3,750 ร 3 ร 12 = 135,000 ๐ฐ |

The Best Mutations to Chase
1. Starstruck (6.5ร) โ Starfall Event
Starstruck is the highest single-mutation multiplier in the game. It triggers during Starfall events, which occur periodically in the 5-minute weather cycle. Starfall is rare โ when it happens, stop whatever you are doing and plant your most valuable seeds immediately.
2. Shocked (4.5ร) โ Thunderstorm Event
Shocked is the second-best mutation and triggers during Thunderstorm. Thunderstorms are more frequent than Starfall but less predictable. Having seeds ready to plant the moment a Thunderstorm begins is key.
3. Snowy (2ร) + Chilled (1.5ร) โ Snow Event
Snow gives both Chilled and Snowy to the same plant for a combined 3.5ร bonus. Snow is more frequent than Starfall and Thunderstorm, making it a reliable mid-tier mutation source during longer farming sessions.
4. Rain Stack โ Flooded + Soaked (3ร combined)
Rain is one of the most common weather events and grants two mutations simultaneously. The 3ร combined bonus is solid and easy to farm consistently.
Best Mutation Combos
| Combo | Total Mutation Bonus | Trigger Events Needed |
|---|---|---|
| Starstruck + Shocked | 11ร | Starfall + Thunderstorm |
| Starstruck + Snowy + Chilled | 10ร | Starfall + Snow |
| Starstruck + Flooded + Soaked | 9.5ร | Starfall + Rain |
| Shocked + Snowy + Chilled | 8.5ร | Thunderstorm + Snow |
| Snowy + Chilled + Flooded + Soaked | 6.5ร | Snow + Rain |
| Flooded + Soaked (Rain only) | 3ร | Rain |
| Snowy + Chilled (Snow only) | 3.5ร | Snow |
