How to choose terrarium plants – top 5 groups of species
How to choose the perfect terrarium plants? What are the most popular species and what do you need to know? There are several large groups of plants that are suitable for terrarium designs – succulents, cacti, ferns, mosses, flowering plants, etc.
Some people prefer to plant a large number of different species, but it will depend on the size of the container itself. Small containers are meant to be placed on a coffee table or a windowsill, and usually accommodate from one to three plants, rarely five. Large containers allow you to grow a dozen of species, but they require a special place and special climate control so if it is your first terrarium, it is better to choose a compact version. When selecting the species for your container, you need to choose them not only for the decorative appearance, but to understand their preferences for the type of soil, the requirements for lighting, humidity and care. Of course, the neighboring plants should have the same requirements. Terrarium plants are divided into two large groups:
Moisture-loving plants requiring stable or high humidity of soil and air.
Succulents and cacti that require minimal care.
Here are some of the most popular terrarium plants:
Miniature ferns like Asplenium, Pteris, Adiantum can be grown by themselves or combined with mosses. Ferns are a great background for other plants as well.
Mosses are a large group of species used not only in terrariums but in aquascaping as well. They require constant humidity and rather moisty conditions. It is also advisable to use acidic soil which must be layered over a common substrate. Sphagnum (Peat moss) creates a dense and very bright coating and is among the most popular species. Other recommended species are Campylopus introflexus, Climacium americanum, Dicranum scoparium, Hypnum imponens, Thuidium delicatulum.
Crotons are another large group of plants suitable for terrariums. Their leaves with beautiful colors and patterns add visual interest and color to any composition. It is true, that when we say crotons we imagine large varieties with massive leathery leaves, but there are compact species with narrow and smaller and these are the dwarf varieties, for example, gold dust croton. You need to keep in mind that crotons like bright light, so it is best if you grow them in open containers.
Cacti come in a huge variety but in order to thrive, they need regular airflow and low humidity. Their ability to live in almost completely dry conditions makes them ideal terrarium plants and whether you choose to combine only cacti species or add succulents, you will have a wonderful mini garden. Cacti are the choice when you want to arrange desert landscapes with minimal imitation efforts. Astrophytum, Echinocactus Grusonii, as well as Mini Echinocactus Grusonii, Gymnocalycium Mihanovichii (Yellow Top Moon Cactus) are just some of the species that you can choose from.
Succulents are ideal as terrarium plants. They prefer a low level of humidity and good draining, so it is better select an open container so that there is a good airflow. Sempervivum, Echeveria, Agave, Aloe, Haworthia – these are among the most popular succulent varieties for terrariums.
