In this guide, you will learn more about the two common types of terrariums and discover the best terrarium plants for each type.
If there was ever an MVP for the plant world, it would hands-down be terrariums. Exploding in popularity, it is easy to see why so many people have them. Requiring virtually little to no care, they are the perfect choice for aspiring plant hobbyists with busy schedules (or those who struggle to keep up with watering).
What is a Terrarium?

According to The English Garden, terrariums were invented completely by accident when London doctor Nathaniel Ward was monitoring the life cycle of insects in a closed jar and found beautiful, tiny plants emerging and flourishing.
Looking at a 30,000 feet view, terrariums can be described simply as enclosed ecosystems.
Beginning in sealed glass jars, terrariums give plants the unique opportunity to thrive and grow in their own separate space. This is especially good news for busy plant hobbyists–as the nature of these ecosystems is that they are virtually self-sustainable and require very little watering and maintenance.
Which leads us to why you need them–terrariums are great, low-maintenance ways to showcase beautiful plants. They are one of the easiest ways to maintain and grow plants, and they don’t take up much space (in fact, all of mine are hanging from the ceiling), which makes them a must-have for those with smaller spaces.
There are two types of terrariums: open and closed. Keep reading to learn more about each!
Open terrariums provide plants with an enclosed space to grow and thrive. However, different from their ancestor, open terrariums do not require a lid.
While this may not seem like a big deal at first, it does drastically change the ecosystem inside the terrarium. Not having a lid means that the plant is exposed to the air and environment outside the ecosystem, which works especially well for cacti and succulents.
The pros to an open terrarium is that it can be a great way to showcase not just succulents, but also plants that need a lot of space to grow, like the string of pearls.
The downside is that they need to be watered more often than closed terrariums due to being exposed to air. If you choose to go with an open terrarium, you will need to water your plants about once a week, or whenever the soil is dry to the touch.
Closed terrariums make amazing centerpieces, as they display a thriving ecosystem that you can watch, and yet have very little to do in order to keep it going. Being completely enclosed guarantees a moist and warm environment, making it the perfect home for plants that require higher levels of humidity (such as ferns, mosses, & English ivy).
What might make a closed terrarium a better option for you is that they require little to no watering. Unlike their younger relative, closed terrariums feature an ecosystem that is completely self-sustaining. Water continuously circulates within the terrarium, making plants able to independently grow and thrive without you needing to constantly check their soil.
Also, a majority of plants that like closed terrariums enjoy medium-low levels of indirect sunlight–meaning that you can have a thriving terrarium garden no matter how much sun your space gets.
The only downside of closed terrariums is that your plant choices are limited, as cacti and succulents do not do well in these closed ecosystems.
You’ve decided between which type of terrarium you want to make. Before you go filling up your cart with beautiful plants, however, there are a few things you will need to ensure that your new plant babies have the perfect environment to grow and thrive.
Let’s take a look at how you can get started building your perfect terrarium garden.
