Terrariums are similar to aquariums, but instead of hosting fish and other aquatic life, terrariums contain plants. Arrangements of rocks, moss, plants, and even small decorative items inside a terrarium make striking table centerpieces, wall art for the home, or desk decorations for the office.
The best terrarium for your needs depends on the types of plants you’d like to grow, whether you prefer an open or closed terrarium, and the home or office space you’d like to embellish. In any case, the best terrariums can accommodate a wide variety of plants to create a beautiful indoor garden.

What to Consider When Choosing the Best Terrarium
Before you purchase the best terrarium for your needs, there are a few key decisions to make first. Because some terrariums come with growing kits, for example, you’ll want to think about whether you want the rocks and other accessories that come with it. Also consider the materials from which the terrarium is made, how large or small a vessel you want, and whether it’s open or closed. When creating an indoor garden, evaluating the following features will help you choose the best terrarium for your plants.
Most terrariums for indoor gardens are made of glass. Glass is easy to clean, allows a clear view of the plants inside, and complements just about every decor. However, some terrariums, such as wall-hanging or freestanding planters, may be complemented by materials such as metal or wood, which is both utilitarian and enhances the look of your indoor garden.
It’s common to find glass terrariums in geometric shapes, often accented with metal trim around the sides of the vessel. The metal is most often available in black, gold, or silver finishes to match most household decor.
Size and Shape
The size and shape of your terrarium are both important considerations, particularly if you already know where you want to place the terrarium or already have the plants that will grow inside.
Those who are shopping for a terrarium to house the plants they already have should research how tall the plants will grow and how much space they need. Bear these figures in mind as you shop, and make sure the size and shape of the new terrarium can accommodate your plants’ growth.
Vessels of certain shapes and sizes are better for certain kinds of plants. For example, smaller terrariums, whether geometric or globe shaped, are great for succulents. Meanwhile, larger terrariums may be more appropriate if you plan on growing taller plants, such as bamboo. If you’d like to grow plant cuttings, look for a terrarium in a cylindrical shape.
Freestanding terrariums simply sit on a counter, table, or desk without a stand. These tend to be smaller planters best for plant cuttings, succulents, or other smaller plant varieties.
Wall-mounted terrariums typically consist of glass plant containers housed in some kind of metal or wood holder which attaches to the wall. Hanging planters are available in different shapes, including globe or geometric, and can bring your indoor garden to new heights.
The form of terrarium that is right for you really depends on which plants you’re hoping to grow and whether you’d prefer to grow them on a tabletop or have them hanging from the wall or ceiling.
Open vs. Closed
Terrariums can also be open or closed, which allows the gardener to control the humidity level of the plants’ growing environment. Most globe-shaped terrariums are open at the top or on one side. In these terrariums, plants have access to fresh air and grow at the ambient humidity level of your indoor space.
Some larger terrariums may have lids, enabling you to open or close as needed to adjust the humidity inside. Open the top if your terrarium is too humid, or close it for plants such as ferns, air plants, and carnivorous plants that thrive in higher humidity levels.
Stand-Alone vs. Kit
Shoppers in the market for the best terrarium may notice that some of these planters are sold by themselves and do not include soil, seeds, or plants, while others terrariums are sold as kits. Kits typically contain everything you need to get started with your terrarium, such as soil, rocks, moss, and seeds.
A terrarium kit is a terrific, fuss-free way to get started with an indoor garden—it makes a great gift, too. These kits are an especially fun activity for kids, as they can begin setting up their growing environment as soon as it arrives.
Seeds are typically packaged with terrarium kits, too. If you don’t want to wait for seeds to grow or have already picked out the specific plants you want to grow, a stand-alone terrarium may be a better choice for your needs.

Another terrific benefit of D’Eco’s planter is its height; it’s tall enough to accommodate bamboo, mini orchids, and other plants that need a bit of clearance. Be aware, this terrarium isn’t watertight, so you will want to line it with an absorbent material at the bottom to prevent leaks, or use it for decorative purposes only.
Measuring 6.89 inches by 5.91 inches by 6.89 inches, this pentagon-shaped terrarium is ideal for small plants, such as air plants and succulents.

These tiny terrariums can house succulents, air plants, moss, or small ferns.
Though each terrarium has an opening that makes watering and maintaining plants easy, be aware that the vessels are not watertight. Therefore, plants that can be watered with a spray bottle will work especially well with these Mkono minis.

Many types of plants can flourish in a terrarium, from moss and orchids to ferns and bamboo. Succulents are also popular choices for these vessels because of their compact size and the unique arrangements you can create with them.

Get a terrarium that’s big enough to accommodate the plants you want to grow. Succulents can do well in small terrariums, while bamboo, ferns, or orchids will require larger ones.

In the right conditions and with the right care, a terrarium can last indefinitely.
Q. Where is the best place to put a terrarium?
To determine where to place your terrarium, think about the plants you’re growing.
