Aurora Mutation Grow a Garden: 90x Multiplier Guide [2026]

What Is the Aurora Mutation in Grow a Garden

Aurora is a weather mutation in Grow a Garden, the Roblox farming game. It raises the sell value of a fruit by 90 times. You cannot buy it or spray it on. It appears only while the Aurora Borealis weather event is running, and it was added on June 28, 2025.

This page covers the original Grow a Garden. Grow a Garden 2 is a separate game with its own Aurora event, so do not carry the number over. Every other mutation is listed on the Mutations hub.

Facts that several sources agree on are marked as confirmed. Facts that sources dispute or leave out, such as rarity, tier and the Cosmic multiplier, are marked ⚠️ PENDING and carry no number outside the per-source tables.

Aurora Mutation Multiplier: What the Sources Say

Seven outside sources and our own Astral guide give Aurora as 90×. One Sportskeeda page lists a decimal value instead, so the exact figure is ⚠️ PENDING until it is checked in game. The older entry in the GAGdata mutation database says 8×, and no outside source backs it. The table shows every source.

Aurora Mutation Value Examples

The multiplier applies to the base value of the fruit. The rows below multiply a base value by 90. The mutation database lists every other mutation.

How to Get the Aurora Mutation

Aurora Borealis Steps

1. Plant and grow crops. Only crops that are growing in your garden can receive Aurora. Keep your best fruit planted.
2. Wait for the Aurora Borealis event. The weather event is random and has no timer or warning. Guides call it rarer than rain and snow.
3. Stay in the server. The event lasts a few minutes. Aurora is applied to crops while it runs. You cannot trigger it with a spray, gear or a pet.
4. Check your fruit. Sportskeeda says an Aurora fruit shows a blue and purple tint and gives off smoke. Harvest it before you sell.

Aurora is a crop mutation. Pets have their own mutations, covered in the pet mutations guide.

Aurora Borealis Frequency by Source

No source gives an exact chance or schedule. Event frequency: ⚠️ PENDING.

Release Update by Source

Sources agree on the date but not on the update name. Update name: ⚠️ PENDING.

Aurora and Cosmic: The Celestial Fusion

A crop that holds both Aurora and the Celestial mutation fuses into Cosmic. Sportskeeda says both originals are removed when this happens. The Astral mutation guide follows the chain further.

Sources disagree on the Cosmic multiplier, so it is ⚠️ PENDING here.

Aurora Mutation Stacking Guide

Aurora stacks with other mutations the way any weather mutation does. The in-game formula comes from the mutation stacking guide: Total = Base × Variant × [1 + sum of mutations − N], where N is the number of mutations in the sum. The community shorthand multiplies every mutation instead.

The two forms match until a stack has more than one mutation in the sum. Then the gap grows fast, as the Shocked row shows. Run your own fruit through the mutation calculator.

Best Crops for the Aurora Mutation

No crop is confirmed as the best match for Aurora. The event picks growing crops at random, so keep your highest value fruit planted when it starts, because the multiplier applies to the base. Best crop pairing: ⚠️ PENDING.

Aurora vs Other Mutations

These figures come from our mutation database. Aurora at 90× sits between Rainbow and Celestial. Rarity and tier are held back until they are confirmed. See the mutation tier list for the full ranking.
