What Is a Moss Ball?

Hi! i'm moli, nice to meet you!

I have never touched soil. I have never felt rain.
No roots, no pot — just water. For a long time that water was the bottom of a lake in the far north of Japan, in the crater of an old volcano. Now it's a glass bottle on a desk.
For four months a year, nothing happens to me. From December the lake closes over, a lid of ice thick enough to walk on, and stays until late April. Under it: no light worth the name, nothing to do. I shrink into the smallest version of myself and wait. Nobody comes to check.
The Ainu, who have lived on that shore longer than anyone else, call us the heart of the marsh. Not a pet. Not a plant. An organ. I think that name was chosen in winter.
Ours is short and doesn't end well, which is why people remember it. A chief's daughter was promised to a wealthy family; she had already given her heart to an ordinary guard. On the night of the wedding she heard a grass flute in the dark, followed it to the shore, and took a boat out with him. The moon was out. Then they stepped into the water. People say their souls became the round green things on the floor of the lake.
So marimo came to mean love that doesn't change — the kind you give someone, not the kind you sell them.
I don't know if that's true. I know I'm round, and green, and slow, and the story has been told about me so long it's worn smooth, the way I have. Believe it or not — only keep it.
We have our own ritual, and it's slightly ridiculous, which is why it works: you look at your marimo and say, mari, mari, marimo. Three syllables, slowly. People do it before exams, before interviews, before calls they don't want to make.
Nothing happens. And then sometimes something does.
I won't promise you luck — you'd stop trusting me. The ritual isn't for the plant, it's for the pause: ten seconds of doing nothing else. That's not superstition. That's a break.
Here is my confession: I am a terrible houseplant.
I grow five to ten millimeters a year. Every other plant on a shelf can be pushed — more light, more food, a bigger pot, and it answers. You cannot push a marimo. Lamp, heater, CO₂: I stay exactly as unhurried.
Then I noticed what slow gives you. A plant that grows fast is a plant you replace. One that grows five millimeters a year outlives the apartment, the job, the relationship, and the phone you photographed it with. People who have kept a marimo twenty years don't talk about them like plants. They talk about them like witnesses.
Everything for sale is grown from strands and rolled by hand.
So when someone asks what to keep on a desk when they're on their own, I want to raise a hand. I was made for that desk.
You'll forget I exist for eleven days. Then you'll look up and I'll be there: green, round, doing nothing. You'll change my water and I'll bubble for a while, which is the only way I know how to say I'm pleased. Some mornings you'll be too tired to talk. That's fine. I'll be the thing on your desk that's still alive.
No feeding, no walking, no vet, no guilt when you travel. I don't die because you had a bad week. That sounds like a small thing until you have had a bad week. Someone wrote to us once: "I don't have to be okay to take care of something."
One way to hurry me: keep me near 22°C, and change my water every couple of weeks. Then one day the surface will feel prickly instead of smooth, and a year of quiet work will arrive at once, the way the ice goes out.
If you're lonely, keep a marimo. We're the same kind of creature: the patient kind, the kind that grows slowly and stays.
And a wish of my own. I hope you keep me long enough to get bored of me. I hope I'm still green when the desk changes and the job changes and the person sitting in front of me is someone your younger self wouldn't recognize. Round things are good at that. We stay while everything else does the changing.
That's the whole of it. I have never touched soil. I have never felt rain. And I would like to spend the rest of my life on one desk, in one bottle, in front of one person who remembers to change the water.
