Looking for a unique, living gift that’s easy to care for and full of charm? The Marimo Moss Ball Eco-Glass Jar Kit is a wonderful choice for all ages. As a UK supplier of Marimo moss balls, we offer a beautifully packaged, eco-friendly kit perfect for beginners, children, and plant lovers alike. Whether you’re after an unusual birthday gift, corporate giveaway, wedding favour, or bulk wholesale order, this kit ticks every box.
Despite its name, the Marimo moss ball isn’t moss—it’s a rare type of spherical green algae called Aegagropila linnaei. Naturally occurring in cold freshwater lakes in Japan, Scotland, Iceland, and beyond, these algae balls roll along the lakebed and grow into velvety, perfectly round forms. In Japan, Marimo is considered a symbol of love and luck, with a famous legend of two lovers whose hearts turned into Marimo to stay together forever.
Absolutely. This kit is ideal for beginners because Marimo moss balls:
Require minimal maintenance
Thrive in low light
Live in plain cold tap water
Grow slowly (about 5mm per year)
Don’t need soil or fertiliser
Can survive for decades (even 100 years!)
With an illustrated care sheet and step-by-step guide included, anyone can enjoy the magic of Marimo—no green thumb required.
Yes! Marimo moss balls are:
Pet- and child-friendly
A brilliant introduction to nature and responsibility
Perfect for children to build their own water pet world
Small and mess-free
Our kits come with everything needed to set up a little aquatic world, making them a fun and educational experience for kids and families.
Marimo moss balls are aquatic by nature and should be kept submerged in water. However:
They can survive up to 7 days outside water if stored in a sealed plastic bag to retain moisture.
For longer storage, place in a jar with cold water and follow regular care steps.
They should not dry out or be exposed to direct sunlight or heat.
If gifting later, simply store the moss ball in water and re-pack it when ready.
Your Marimo kit contains:
Healthy Marimo Moss Ball (1–3 cm)
1x Eco-glass jar with cork lid (Height 12cm)
Coloured sand or decorative stones
Natural shells
A beautifully printed care guide with setup instructions and folklore
Illustrated information about the Marimo legend to make care even easier and more meaningful
All items packed safely and sustainably
We also offer custom bulk orders—perfect for corporate gifts, wedding favours, or event giveaways. Email contact@highlandmoss.com for a quote.
Why is my Marimo floating?
Freshly moved moss balls sometimes trap air. Gently squeeze it while submerged to remove air bubbles—it will sink again.
Is brown or dark green discolouration normal?
Yes, some darker patches are natural, especially on younger moss balls. However, yellow or light brown patches can indicate too much direct light or water that is too warm. Move your Marimo to a cooler spot out of direct sunlight and replace the water with fresh, cold tap water, rainwater, or clean natural lake water. Avoid placing it near radiators, sunny windowsills, or heated tanks..
Can Marimo be kept in an aquarium?
Yes! Marimo moss balls cohabit peacefully with fish and shrimp, reduce algae, and look beautiful in water features or planted aquariums.
How often should I change the water?
Every 2–3 weeks. Use cold tap water, rainwater, or fresh, clear lake water if available. Avoid chlorinated or hot water.
Do I need to add plant food or fertiliser?
No. Marimo balls do not need fertiliser—they thrive in clean, cold water.
The Marimo kit makes a beautiful, lasting gift:
🌸 Wedding favour symbolising love and happiness
🧑💼 Corporate gift for employees or clients
🎂 Birthday surprise for plant lovers
🎄 Christmas stocking filler
🏡 Housewarming gesture with meaning
Each kit can be personalised with your choice of sand or stone colours and a gift note at checkout. Invoices are never included in gift orders.

We use recycled packaging where possible
All moss balls are carefully inspected by hand
We source ethically and avoid invasive species issues

If you ever need to dispose of your moss ball, please do not flush it. This can damage local ecosystems. Instead:
Place it in a sealed bag and dispose in general waste
Or, dry it out fully and use as decoration (it won’t rot or smell)
Hi, thank you for your question. No, these lids do not light up. You could swap the lid out with something with a light if you choose, but if you do I would advise you ensure the water level is a little lower for safety.
Thank you, Craig
Craig answered on December 9, 2024 store managerHi,
Thank you for your question. You can keep the sand and reuse it. To change the water, you can lightly tip the jar with your fingers held over the top to stop anything other than water falling out. You can also remove the ball then rinse through the jar until the old water has overflowed out.
Any decorations like sand, gravel, shells etc are fine to reuse, just clean as required.
Hope this helps!
Craig answered on December 28, 2023 store managerHi Jeanette,
We would recommend keeping them in a jar or container with cold tap water, it doesn’t have to be anything fancy a takeaway tub or jam jar is fine. Then before gifting them they could be put back in the resealable packaging up to a week in advance.
I hope this helps,
Craig
Craig answered on November 3, 2023 store managerHi Cyane,

The jar and the marimo’s are bigger than I expected, which is a lovely surprise. I got this as a gift for my other half and he’s very pleased with them. They’re so cute, and I love that is comes as a little kit rather than pre-assembled
