What Sets Us Apart


A bowl of bismuth

We also offer colorful rocks and minerals, like this bowl of Bismuth!

Did you know our classes are now the most popular “classic terrarium” classes in the entire world?

It's true. Our survey of terrarium shops in all the major cities across the U.S. and around the world reveal that Roosevelt's Terrariums now offers more actual classes per week, with more actual attendance in each class, than any other terrarium shop in the world. Why might that be?

It is because here at Roosevelt's Terrariums we teach you how to plant a TRUE TERRARIUM; a CLOSED, WET, SCIENCE-BASED, LOW-MAINTENANCE terrarium. Not just another wide-open glass planter, with nothing but a succulent or an air plant.

Each of our terrariums is a self-perpetuating, tropical ecosystem. In other words, a TRUE TERRARIUM WITH A LID. Because, as we say around here:

“If it doesn’t have a lid, who you trying to kid?
It’s not a terrarium.”


There's More to Terrariums Than You Realize



Another reason our classes are so popular is because we begin each class with a brief history, then an explanation of the basic science, a presentation of the proven principles of terrarium design and finally, clear instructions on proper terrarium care and maintenance.

This way, you, and your friends, end up with beautiful terrariums that will thrive for many, many years. And we guarantee it.

Your terrarium will look as good as our own, and we’ll even back it up with our unique No-Fault Terrarium Warranty and Free Maintenance. We simply will not let your terrarium fail to thrive.
