The Strange Plant unlocks a hidden achievement in Honkai: Star Rail. See its location and use in our guide!

The Strange Plant Location

Upstairs in the Base Zone

You can find The Strange Plant upstairs in the Base Zone of Herta Space Station. There are two people standing near it and seemingly observing it, which makes the plant hard to miss when you climb up the stairs.

How to Use The Strange Plant

Interact With it to Water the Plant

To proceed, simply investigate the plant when it prompts you to. You will be given three options at the end of the dialogue and you will be able to choose what to water the plant with. However, all the options will lead to you giving it some pure water.

Come Back the Next Day

After watering the plant, it will tell you to come back tomorrow for its reward. This means that you should come back the next day or the next server reset then talk to the plant again.

You will get a Praise of High Morals after your first dialogue with it. It will have a dialogue with you again tomorrow and right after you can claim your rewards.

The Strange Plant Rewards

Get Hertaeum, Praise of High Morals, a Seed, and the Achievement

Once you finish this hidden quest, you will be able to receive some Hertaeum, another Praise of High Morals, and a Seed material used for synthesis. You will also receive the Green Thumb Achievement.
