Terrariums are plant-filled glass containers, with or without a transparent lid, are generally decorated with mixed plantations of miniature plants, creating a bubbles of greenery.
Essentially a mini and self-contained plant ecosystems growing in a glass jar. They’ve taken the gardening world by storm, and it’s easy to see why.
Maybe because you can play with the colors of the grass, of the plants and even of the soil and gravel? Maybe because you can grow your plants in decorative glass containers?
Maybe because they are miniature gardens, and they can look very exotic? Maybe because you can express your artistic qualities?
Whichever the reason, the fact is that terrariums are easy to install, low-maintenance and beautiful decorative object for bringing a touch of greenery to your interior.! But not all plants are suitable for your terrarium…
So, what plants grow well in a terrarium? In terrariums, you need to use slow growing miniature plants, visually striking and original houseplants and also plants that will adapt to the shape and opening of your terrarium. Many succulents, insectivorous plants and small houseplants are suitable.
Then, you should know that not all terrarium models correspond to all plants. So, choosing the best terrarium plants will depend on whether your terrarium is open or closed.
Open terrariums are ideal for plants that prefer arid, dry conditions like succulents, air plants and cacti. On the other hand you should build your closed terrarium using tropical plants that love humidity and heat like mosses, epiphytes, ferns, carnivorous plants and some ornamental plants like the fittonia.
Depending on these conditioning options, the choice of plants and maintenance will be different.
So, just read on and find which plants you can “mix and match” in your open or closed terrariums to turn that empty glass vessel into a wonderful small garden!
Types of Terrariums
First of all, you need to know that there are different types of terrariums. Of course, the shape, depth and color make a difference, but in practical terms what matters most is the opening.
Also the depth of the terrarium is important though; shallow terrariums are not suitable for plants that do not like their “feet” wet, like succulents. Stagnant water can cause root rot and spell the death of your little green friends.
So, choose your container carefully, or, if you already have one you want to recycle, choose your plants carefully!
