Tempestuous Mutation in Grow a Garden
Last updated September 2026
Quick answer
Tempestuous is a x12 mutation in Grow a Garden — rank #108 of 169 by multiplier. It is a combination mutation: not found in the wild at all — you fuse other mutations into it. Combining Windstruck and Twisted mutation.
On the highest base-value crop in the game (Christmas Tree, 451K coins) this multiplier turns a harvest into 5.4M coins — and held through the chain it ends at Maelstrom x100.
Tempestuous is a x12 combination mutation: you never find it in the wild, you build it by stacking two common weather effects on one unharvested crop — Windstruck (x2, from Windy) and Twisted (x5, from Tornado).
On the multiplier chart x12 sits mid-table (rank 108 of 169), so Tempestuous is not usually the payout itself. It is the only ingredient of Maelstrom (x100) — the top of the Windy → Tornado chain — which is why players deliberately park a Tempestuous crop in the ground and wait instead of harvesting it.
What Tempestuous is worth on the best crops
Base sell value × x12 for the ten highest-value crops in Grow a Garden. Weight bonuses and any other mutation on the crop multiply on top of these numbers.
| Crop | Rarity | Base value | With Tempestuous | Added |
|---|---|---|---|---|
 Christmas Tree | Prismatic | 451K | 5.4M | +5M |
 Gingerbread Blossom | Transcendent | 226K | 2.7M | +2.5M |
 Frostwing | Prismatic | 181K | 2.2M | +2M |
 Parasol Flower | Mythical | 181K | 2.2M | +2M |
 Gift Berry | Divine | 170K | 2M | +1.9M |
 Multitrap | Divine | 162K | 1.9M | +1.8M |
 Wispwing | Prismatic | 162K | 1.9M | +1.8M |
 Pinkside Dandelion | Divine | 160K | 1.9M | +1.8M |
 Amberheart | Mythical | 158K | 1.9M | +1.7M |
 Wereplant | Divine | 153K | 1.8M | +1.7M |
How to get the Tempestuous mutation
Combining Windstruck and Twisted mutation.
- 1Get Windstruck first: leave crops planted through Windy weather so they pick up the x2 tag.
- 2Keep those crops unharvested and wait for Tornado. Twisted (x5) is applied during Tornado weather.
- 3Do nothing when the second tag lands. The fusion is automatic — the moment a crop holds both Windstruck and Twisted it becomes Tempestuous x12.
- 4Decide whether to sell or push on. Selling gives x12; holding gives you the only route to Maelstrom x100.
- 5If you are chasing Maelstrom, repeat the previous step rather than harvesting: Maelstrom is fused from Tempestuous plus another mutation, so the Tempestuous crop has to survive.

Tempestuous in the mutation chain
Tempestuous is step 1 of 2 in a chain that tops out at Maelstrom x100. Every step consumes the one before it, so a crop can only be at one rung at a time.

Can Tempestuous stack with other mutations?
Tempestuous replaces its own ingredients. Windstruck and Twisted disappear when the fusion happens — the crop carries Tempestuous, not all three at once. That is why x12 is not simply 2 + 5.
Beyond that it behaves like any other mutation on the crop: it sits alongside whatever growth variant the crop has and can itself be consumed by the next fusion step.

Tempestuous FAQ
How do you get the Tempestuous mutation in Grow a Garden?
Leave a crop unharvested through Windy weather so it gains Windstruck (x2), then keep it in the ground until Tornado weather applies Twisted (x5). The two fuse into Tempestuous x12 automatically on that crop.
What is the Tempestuous multiplier?
x12. That is the sell value multiplier applied to the crop base value — a 451,250 base crop becomes 5,415,000 coins.
Do I need both Windstruck and Twisted?
Yes. Tempestuous has no other source, and neither ingredient can be bought or substituted. Both come from weather, so the whole thing depends on two separate event windows landing while your crop stays in the ground.
Is Tempestuous better than Maelstrom?
No. Maelstrom is x100 and is fused from Tempestuous, so if you can afford to keep waiting, Tempestuous is worth more as the ingredient than as the harvest.
Can Tempestuous stack with other mutations?
It coexists with variants and other layers on the crop, but fusing it forward into Maelstrom consumes it in the same way it consumed Windstruck and Twisted.
What is the multiplier of Tempestuous in Grow a Garden?
Tempestuous is a x12 mutation, which puts it at rank #108 of 169 mutations by multiplier. 0 other mutations share the same x12 value.
Can you get Tempestuous any other way?
No. Tempestuous comes from not found in the wild at all — you fuse other mutations into it. It has no second source in the mutation list.
