Open Terrarium Plants

Open-terrarium plants suit ventilated glass displays with fresher airflow and varied moisture conditions. Compact ferns, Peperomia, Pilea and Cryptanthus create leafy miniature landscapes, while succulents and other drought-tolerant plants suit airier mineral displays.

Terrarium setup

Build the right terrarium base layer

Closed terrariums need a stable base that balances moisture, structure and hygiene before the planting layer goes in.

Details & Care

Open terrarium plants for airy, compact displays

Open vessels suit two distinct planting styles. Dry open terrariums can hold compact succulents and other drought-adapted plants. Humid open displays can hold miniature foliage plants, selected ferns and creeping species that share a steadier moisture range. Plants from these two groups need separate substrates and watering routines.

Planting by growth speed and scale

Mature height and spread should shape the design at the planning stage. Slow rosettes preserve open space, while creeping stems gradually soften stones and hardscape. One focal plant combined with low companions creates a clear layered view. Fast vines need enough room for regular trimming.

Leaf size affects the sense of scale. Fine foliage creates depth near the glass, while one broader leaf gives the eye a resting point. The container opening also influences access for watering and maintenance.

Root zone and air exchange

A porous substrate supports air around the roots in a vessel with limited depth. Containers without drainage holes require restrained watering because excess water cannot leave through the base. Dry and humid planting styles work best in separate vessels.

Spacing, planting depth, mature spread and compatible moisture use shape a stable open display. Open vessels lose moisture more quickly, so the watering guide helps replace a fixed schedule with checks based on substrate, plant type and season.

Open Terrarium Plants FAQ

What plants work best in open terrariums?

Open terrariums suit compact plants that enjoy bright, indirect light, moderate to higher humidity and steady airflow. Small ferns, trailing tropical plants, compact Peperomia, selected Pilea, Cryptanthus and other low-growing foliage plants can work well, as long as the vessel stays open or well ventilated.

Are open terrariums easier than closed terrariums?

Open terrariums are usually easier to adjust because you can water, trim and rearrange plants without disturbing a sealed environment. They dry out faster than closed terrariums, so they need more regular checking, but they are also less prone to stale, trapped moisture.

Can I use moss in an open terrarium?

Yes, moss can be used in an open terrarium as a soft surface layer, natural accent or finishing detail. It should not stay constantly soaked, especially in a ventilated setup. Use it to cover bare substrate, soften edges and add texture rather than treating it as a permanently wet carpet.

Die Pflanzen waren prima verpackt und ein heatpack war im Paket enthalten. Die Lieferzeit hat 2 bis 3 Tagen gedauert, was aus meiner Sicht wirklich gut ist. Alle drei Pflanzen haben die Lieferung gut überstanden. Ich habe mich auf Hoyas spezialisiert und habe schon die nächsten Pflanzen meiner Wunschliste auf der Website gefunden. Daher wird die nächste Bestellung nicht lange auf sich warten lassen.

The plants are carefully packaged and arrive in great conditions (I’m based in Spain) and they’re always there to help in any way they can with your purchase.I have and will always recommend Foliage Factory to every friend I can. I’m not only satisfied with their plants and prices, but their customer service is exceptional.

Very healthy and well packed plant. Unfortunately there was one plant that ordered couldn’t be delivered as it was out of stock hence 1 star less.

Sam

Die Sendung kam leider in keinem guten Zustand bei mir an, kann passieren. Habe mich darauf hin sofort an Foliage Factory gewandt und habe selten einen so guten, schnellen, freundlichen und kulanten Kundendienst erlebt.

Frauke

Everything arrived in good condition and very well packed - it wasn't easy with a fragile plant and a heavy bag of substrate. I recommend it!

Bester online-Pflanzenhandel den ich kenne (habe davor 4 andere ausprobiert). Eine teure Pflanze wurde beim Transport beschädigt und mir ersetzt. Der Kontakt dabei war auch sehr nett (danke Jan) und hat mir gut geholfen. Die anderen Pflanzen sind in einem sehr guten Zustand, keine Schädlinge, super Bewurzelung. Nur zu empfehlen! :)

The plants have arrived in perfect condition, the roots and the foliage so so healthy! I had problem with 1 plant out of 16 and they have responded to my email almost instantly and the issue was resolved straight away. I'm really impressed and satisfied, definitely getting more plants from them again!
