Meet the Marimo. Spherical moss, ball seaweed, or moss balls (and a few other names), Marimo are actually a special and rare kind of algae (not moss) that grow into balls – and look like … Underwater Pom Poms! They feel and look like wet wool felt 🙂
Colonies of these balls form underwater in lakes in Japan, Iceland, Scotland, Estonia and Australia. I bought mine from an Aquarium Supply shop, who assure on their website that they are obtained in Australia, sourced from certified sellers and in no way imported illegally.
My guys are about 6cm and 8cm across. Although not a usual house ‘plant’, they can be kept in vessels to bring a little green into your home and are very easy to care for.

So, do you want your own underwater pom pom now 🙂 That is the nickname we have for them and it suits don’t you think! Since this week is Pom Pom themed, I thought these would be a cute addition. They are just adorable!
