If you have watched someone pull a Voidtouched fruit worth 135× its base value while you are harvesting plain crops, you already know mutations are the actual game inside Grow A Garden. They determine whether a crop sells for a few hundred Sheckles or several billion.

Not every mutation has the same odds, though. If you want a full breakdown of which mutations are worth chasing, see our best mutations guide. Some trigger during common weather. Some need specific pets. A handful only appear when a developer manually starts a server event. This guide breaks down which mutations are the rarest — with verified multipliers and honest probabilities — so you know exactly what you are chasing and what it actually takes to get it.

⚡ Quick Answer
🌈
Rarest Natural Crop Mutation: Rainbow (50×) Only a 0.1% random chance during the growing phase. No event required — just brutally low odds.
🌀
Rarest Admin-Only Mutation: Voidtouched (135×) Only spawns during the Black Hole event, manually triggered by developers. Has appeared only a handful of times since launch.
✨
Rarest Pet Mutation: Ascended (0.33% chance) From the Mutation Machine. Gives your pet the ability to apply Dawnbound (150×) to crops passively.

What Is a Mutation in Grow A Garden?

Grow A Garden launched on Roblox in March 2025 and became one of the fastest-growing games on the platform, hitting 9.1 million concurrent players by May 2025. The core loop is simple: grow crops, sell them for Sheckles. But the mutation system underneath is what separates casual players from people earning billions per session.

A mutation is a special effect applied to a crop that changes its appearance and multiplies its sale value. Multipliers stack — meaning one fruit can carry multiple mutations at once, and all multipliers combine multiplicatively. A crop with Wet (2×), Shocked (100×), and Celestial (120×) does not add those numbers. It multiplies them together. The final values become enormous, fast.

There are two types:

  • 🌾
    Crop Mutations — Applied to fruits and vegetables. Change appearance and multiply sell value anywhere from 2× to 240×. Most are triggered by weather events, pets, or random chance during growth.
  • 🐾
    Pet Mutations — Applied to your pets through the Mutation Machine once a pet reaches Level 50. They give pets new powers, like spreading mutations to nearby crops automatically.

The Rarest Crop Mutations — Ranked

Rarity works on two axes: how low the drop chance is, and how restricted the trigger conditions are. Some mutations have a fixed low percentage. Others are locked behind admin-only events that happen unpredictably. Both are rare — but for different reasons.

🌀
Voidtouched
135× Multiplier
● Admin-Only · Rarest Event

Only during the Black Hole admin event. Manually triggered by developers. Has occurred only a few times since launch. Crops get a pink swirl design.

☀
Dawnbound
150× Multiplier
● Admin Event / Ascended Pet

Highest multiplier in the game. Triggered by the Sun God admin event, or passively by a pet with the Ascended mutation (0.33% chance to obtain).

🌌
Galactic
120× Multiplier
● Admin-Only · Space Travel Event

Triggered during the Space Travel admin event. Crops turn purple with a glowing effect. Completely unavailable outside developer-triggered sessions.

🪩
Disco
125× Multiplier
● Admin Event / Disco Bee Pet

Admin-only Disco event gives this. Disco Bee pets can also apply it, making it slightly more reachable than pure admin mutations — but still very rare without the pet.

🌈
Rainbow
50× Multiplier
● Natural · 0.1% Drop Rate

No event needed — just a 0.1% random chance during the growing phase, before the crop ripens. The hardest mutation to get without any admin involvement.

⚡
Shocked
100× Multiplier
● Thunderstorm Weather

Only triggers during Thunderstorm weather, which is one of the rarest natural weather events. A Lightning Rod boosts chances but does not guarantee it.

Voidtouched: The Crown of Admin-Only Rarity

Of all admin-restricted mutations, Voidtouched is what the community consistently calls the rarest. The reason is straightforward: the Black Hole event is manually started by game developers with no predictable schedule. When it triggers, a giant black hole appears in the sky and players literally get pulled toward it. Any crop hit during this event gains Voidtouched — a 135× multiplier with a distinctive pink swirl appearance.

Since launch, the Black Hole event has happened only a small number of times. Players who were online during those sessions with full gardens of high-value seeds made enormous amounts of Sheckles. Everyone else missed it entirely. There is no way to prepare beyond being online and following the official channels for announcements.

Note: As of late 2025, the Space Squirrel pet can now apply Voidtouched passively. However, obtaining and leveling a Space Squirrel to 50, then running it through the Mutation Machine, is still a heavy late-game investment — not a beginner route.

Rainbow: Rarest Mutation Without Admin Help

For players who cannot depend on developer events, Rainbow is the true ceiling of natural rarity. The drop rate is 0.1% — one in every thousand crops that goes through the growing phase might come out Rainbow. That rate does not change regardless of what you do. No weather event, no sprinkler, no tool adjusts that specific probability.

Rainbow only applies during the growing phase, before the crop ripens. Weather events after ripening will not add it. You are entirely at the mercy of RNG during each plant’s growth cycle. The standard strategy is volume: keep as many crops growing simultaneously as possible, using sprinklers to push throughput, so you generate more rolls per session.

Rainbow carries a 50× multiplier on its own. Stacked with Shocked (100×) during a thunderstorm, a single Rainbow fruit hits a 5,000× base multiplier — which on a high-value seed like a Void Lotus becomes billions of Sheckles. That is why players treat a Rainbow drop as a lottery win.

Ascended: The Rarest Pet Mutation

On the pet side, there is no contest. Ascended is the rarest pet mutation in the game at a confirmed 0.33% chance from the Mutation Machine. You are expected to fail over 99 times out of 100 attempts. Each attempt costs significant Sheckles and takes one hour. Use our pet calculator to estimate your Sheckle cost before grinding. Getting Ascended is a long-term, expensive grind — and even then, luck decides.

The reason it is worth pursuing: a pet with Ascended applies the Dawnbound mutation (150× — the highest multiplier in the game) to nearby crops automatically, roughly every 300 minutes. That means passive Dawnbound crops without needing a developer to run a Sun God event. For late-game players, this is the single most powerful farming loop available.

The math: Ascended pet → applies Dawnbound (150×) to crops every ~5 hours → those crops sell for 150× base value passively, indefinitely. The 0.33% chance is the only barrier.

How to Actually Get Rare Mutations

Knowing the rarity tiers is one thing. Knowing how to push your odds is what separates players who occasionally get lucky from players who build reliable output. Here is what works:

  • 🖥
    Follow admin event announcements. Voidtouched, Galactic, and Dawnbound events are announced on the official Grow A Garden Discord and @GrowaGardenRblx on X (Twitter). Community tracking sites like abusetime.dev also monitor scheduled Saturday admin sessions. Being offline when a Black Hole event triggers means missing it completely — there is no other way to prepare.
  • 🌐
    Server-hop for weather events. Different servers run different weather. If you need a Thunderstorm for Shocked (100×) or a Meteor Shower for Celestial (120×), join a server that already has that weather active. Keep high-value seeds planted and sprinklers running before you hop — you want crops in progress the moment you land.
  • 🌱
    Volume is your only lever against Rainbow. Rainbow has a 0.1% chance per crop during growth. The per-crop odds do not change with any tool or method. The only way to increase output is to run more crops per session. Stack your garden with multi-harvest seeds and keep sprinklers running continuously.
  • 🌾
    Plant high-value seeds before chasing mutations. Multipliers apply to base crop value. A 100× Shocked mutation on a common carrot is worth far less than the same mutation on a Void Lotus (12,000 base Sheckles). Always fill your garden with the best seeds you can afford before an event hits — the mutation multiplier does the rest.
  • 🐾
    Use mutation pets for passive coverage. A Disco Bee applies Disco mutations passively without admin involvement. A Space Squirrel can apply Voidtouched. An Ascended pet (if you can get one) applies Dawnbound every 300 minutes. Pets let you generate rare mutations on your own schedule instead of waiting for developer events.
  • 📍
    Position your best crops in the center during admin sessions. When multiple weather events stack during an admin abuse session, crops in the center of your garden plot are most likely to catch mutations from overlapping effects. Put your highest-value seeds there before any session begins.

Frequently Asked Questions

Is Voidtouched or Rainbow harder to get?
They are hard in different ways. Voidtouched depends entirely on developers running the Black Hole event — out of your control. Rainbow has a fixed 0.1% natural drop rate, so you can increase your attempts with volume, but the per-crop odds never change. For most players, Voidtouched is harder because it requires being online at exactly the right moment. Rainbow at least lets you farm it actively.
Can mutations stack with each other?
Most mutations stack and their multipliers combine multiplicatively — not additively. However, Gold and Rainbow cannot appear on the same crop (only one growth-phase variant is allowed). Only one temperature mutation (Wet, Chilled, or Frozen) can be active at a time. All other combinations stack freely. A crop with Rainbow (50×) + Shocked (100×) + Pollinated (3×) + Frozen (10×) alone hits a 75,000× combined multiplier.
Is the Ascended pet mutation worth grinding for?
Only in the late game when you have significant Sheckles to spend. At 0.33%, expect over 100 failed attempts before getting it. Each attempt costs money and one hour. However, the payoff — passive Dawnbound (150×) mutations applied to crops every ~300 minutes — is the most powerful farming loop in the game. If you are farming endgame, it is the highest-ROI investment available.
Do admin mutations have any downside?
No gameplay downside. The only problem is time availability. Admin events are unscheduled in most cases, meaning you can easily miss Voidtouched or Galactic entirely if you are offline. Players who cannot commit to being online during events should prioritize pet-based strategies instead, since those work passively around the clock.
What is the best mutation to target as a beginner?
Gold (20×) is the most realistic starting target — roughly 1% natural drop rate, no event needed. After that, focus on Shocked (100×) by server-hopping during Thunderstorm weather and Celestial (120×) during Meteor Showers. Both are achievable without spending Robux or depending on admin events. Rare mutations like Voidtouched or Dawnbound should not be your main target until you have a solid pet roster and high-tier seeds.

Bottom Line

The rarest admin-only mutation is Voidtouched (135×), only available during the developer-run Black Hole event. The rarest natural crop mutation is Rainbow (0.1% drop rate) — farmable but brutally slow. The rarest pet mutation is Ascended (0.33%), which unlocks passive Dawnbound farming. Chase admin mutations by following announcements, farm Rainbow through volume, and invest in Ascended only when you have the budget to absorb 100+ failed attempts.
