Flask Planted Terrarium

The Flask Planted Terrarium is a generous closed terrarium with a softly rounded flask-shaped glass vessel and cork lid. Individually planted by our team in Edinburgh, each one contains a changing selection of small tropical plants chosen for colour, texture and balance.

At approximately 30cm high, this is one of our larger planted terrariums and makes an impressive living centrepiece for a sideboard, desk, shelf or coffee table. Because every terrarium is planted individually, the exact mix, size and arrangement of plants will naturally vary.

How Does a Closed Terrarium Work?

Once sealed, moisture circulates between the compost, plants and glass, creating a naturally humid miniature growing environment. A well-balanced closed terrarium therefore requires very little additional watering once established.

Where to Position Your Terrarium

Place in bright, indirect light, away from prolonged direct sunlight. Strong sun can quickly raise the temperature inside the glass and damage the plants.

Keep away from radiators and other strong heat sources, and avoid very dark positions. A bright room with plenty of natural light but no intense direct sun is ideal.

How to Water a Closed Terrarium

Closed terrariums should need very little watering. Light condensation on part of the glass is normal and shows that moisture is circulating within the terrarium.

If there has been little or no condensation for several days and the compost appears dry, remove the cork and add only a small amount of water using a fine mister. Water sparingly: it is much easier to add a little more later than to correct an overwatered terrarium.

What If There Is Too Much Condensation?

If the glass remains heavily misted or covered in large droplets throughout the day, remove the cork for a few hours to allow some excess moisture to escape. Replace the lid once the condensation has reduced.

Occasional light condensation is completely normal and does not need to be wiped away.
