The Garden Horizons IGMA Event is the biggest part of the Mythical Update, and it gives you a shot at one of the rarest plants in the game. If you want the Lilystalk, this event is the only way to get it. Here is everything you need to know to make the most of it.

What Is the IGMA Event in Garden Horizons?

The IGMA Event was added to Garden Horizons as part of the Mythical Update on March 14th, 2026. It revolves around a new weather event called Strange Weather, which rolls in every 30 minutes and sticks around for about five minutes. During that window, your crops have a chance to get the Strange mutation.

The Strange mutation does two things:

  • It doubles the sale value of any crop that has it.
  • You can take those Strange-mutated crops to an NPC named Rosalind, who is located at the IGMA platform above the Seed Shop.

When you give her your Strange crops, she rewards you with IGMA Milestone Points.

Garden Horizons IGMA Event Guide

Here is the step-by-step process so you know exactly what to do each time Strange Weather hits:

  1. Once it starts, check your garden for any crops that have received the Strange mutation (green aura around them).
  2. Harvest all your Strange-mutated crops.
  3. Go to Rosalind NPC at the IGMA platform.
  4. Select the "Turn in Strange Plants" option to submit all your Strange crops at once.
  5. Collect your milestone points and check your progress toward the next reward.

That is all there is to it. The process is quick once you get into the habit of staying online during Strange Weather windows.

How IGMA Event Milestone Points Work

Every Strange-mutated fruit you hand over to Rosalind earns you points. The amount you get depends on the rarity of that crop. Higher rarity means more points per fruit.

Every single fruit you turn in counts toward your total, no matter how many sessions it takes. You do not have to rush to 500 points in one go.

All IGMA Event Milestone Rewards

Here is the full list of every reward you can earn by turning in Strange-mutated plants. The final reward, the Lilystalk, is a brand new Mythical plant that you cannot get any other way.

The Lilystalk, which is the biggest prize of this event, is a Mythical-rarity plant, which puts it at the very top of the rarity ladder in Garden Horizons. There is no other way to get it during this update. Since your points never reset, even players who log in casually can build up to 500 over time.
