What Is the IGMA Event in Garden Horizons?

The IGMA Event was added to Roblox game Garden Horizons on March 14, 2026, as part of the Mythical Update.

The event is based around a special weather system called Strange Weather.

How Strange Weather Works

• Appears every 30 minutes
• Lasts for about 5 minutes
• During this time, crops can receive the Strange mutation

The Strange mutation gives two major benefits.

1. Doubled crop value
Any crop with this mutation sells for 2× its normal value.

2. Event progress
You can turn these mutated crops into the IGMA event NPC to earn points.

How the IGMA Event Works

To participate in the event, players need to collect Strange-mutated crops and turn them in.

Follow these steps.

Step-by-Step Guide

1. Wait for Strange Weather to begin.
2. Check your garden for crops with the green Strange mutation aura.
3. Harvest all Strange-mutated crops.
4. Visit Rosalind, the event NPC.
5. Submit crops using the “Turn in Strange Plants” option.

Rosalind is located on the IGMA platform above the Seed Shop.

Each crop submitted gives IGMA Milestone Points.

IGMA Milestone Points System

The number of points you earn depends on the rarity of the crop.

Crop Rarity	Points Earned
Common	1
Uncommon	2
Rare	3
Epic	4
Legendary	5
Mythical	6

Higher rarity crops give significantly more progress.

The good news is that points never reset, so you can slowly progress toward rewards over time.
