The Terrarium Plant Mix is a great pick if you want multiple small plants in one order. It comes with six small plants that are ready to build into a glass terrarium, bottle garden or mini display. The plants are supplied in small nursery pots, typically around 5–6cm, making them suitable for planting in a range of terrariums and miniature indoor displays.

The mix of terrarium plants is not pre-fixed. Rather, it is put together when you order, using whatever is looking its best that season. That means no two sets are quite the same, and you'll usually get a variety of leaf shapes and colours that can range from plain green to pink, red, silver or purple. Every plant is chosen because it stays small and enjoys the moist, sheltered air inside glass. 

If you are building a terrarium from scratch, start with a layer of gravel to collect excess water, followed by a thin layer of horticultural charcoal and suitable compost. As most terrarium containers have no drainage holes, take care not to overwater. Want more small plants? Browse our mini indoor plants.

  • You get six plants in every order for one terrarium or a few small ones.

  • The plants are a seasonal mix chosen from what looks best when you order.

  • Each seasonal selection may include different leaf colours and patterns, with shades ranging from green to pink, red, silver or purple, depending on availability.

  • Every plant in the Terrarium Plant Mix is a compact grower, and each option is picked for its small size and love of humidity.

Watering Water when the top few centimetres of compost begin to dry, then water thoroughly and allow excess water to drain away. Do not leave the plant sitting in standing water, as consistently wet roots can lead to rot. Growth slows in winter, so reduce watering frequency during cooler, darker months.

Best Growing Conditions Grow in bright, indirect light and protection from harsh direct sun, ideally at around 18-26°C, away from cold draughts and sudden temperature changes. Use well-drained soil and make sure excess water can drain freely from the pot. Most houseplants perform best with moderate humidity and should be kept away from strong radiator heat.

Which plants will I get in the terrarium plant mix?

The Terrarium Plant Mix is not a pre-fixed set of plants. Instead, the set is made up from whichever plants look best at the time of year and season in which you order. You'll get six small plants picked for terrarium life, usually with a mix of leaf shapes and colours, so each terrarium looks a bit different.

Do these plants need an open or closed terrarium?

It depends on the plants included in your mix. Most humidity-loving tropical plants suit a closed or lidded terrarium, while cacti and succulents need an open container with better airflow and drier conditions. Check the requirements of the plants you receive before arranging them together.

How much water does a terrarium need?

Terrariums generally need less watering than ordinary potted plants. Closed terrariums recycle moisture and may only need watering occasionally. Check the compost and condensation on the glass before adding a small amount of water. Open terrariums usually dry out faster and may need more frequent watering. Avoid adding too much water, especially when the container has no drainage holes.

Where should I put my terrarium?

Put it somewhere bright, but out of direct sun. Sunlight through glass heats the container fast. This can scorch the plants inside. The ideal spot to place a terrarium would be near an east or north-facing window, but not right against the glass. Turn it every so often so the plants grow evenly.

What does it mean if my terrarium glass keeps steaming up?

A little condensation is a healthy sign, and you don’t need to worry. But if the glass stays fully steamed up all day, that means there's too much moisture inside. In such cases, take the lid off for a few hours, or leave it slightly open, until the glass clears for part of the day.

Top tip

Turn the pot a quarter turn every week or two so the plant develops evenly, and wipe broad leaves occasionally to keep them free of dust. Good drainage is especially important, so avoid leaving the roots sitting in persistently wet or compacted soil.
