1 Review

Continuing on from our Boiling Flask we have extended our Science Vessel range to include the Conical Flask Terrarium collection.

With the wide base and narrow neck, we plant the Conical Flask to ensure there is enough room for all plants to thrive.

The Large Conical Flask is a statement Terrarium when placed alone, however it is perfect. paired with one of its smaller family members, either the Small or Medium Flask.


Each terrarium we build is completely unique, the Large Conical Flask will be planted with a selection of Fittonia, Ivy, miniature Ferns and then finished with Bun moss and decorative stones.

Please note that our Conical Flask collection all come with the measurement lines on the glass.

If you have any specific planting requirements we will be more than happy to help!


Make sure to keep your Terrarium out of any direct sun or direct heat and require little to no watering.

You can read much more about caring for our Terrariums in our Terrarium care section.

Each Terrarium also comes with a physical care guide for you to take home.

About Terrariums

Almost un-killable, terrariums require virtually zero maintenance.

In their closed eco-system, the plants become self-sustaining as the glass stops any of the humidity created from escaping keeping the plants nourished and happy.

They are perfect for any home and are best out of direct sunlight.
