As long as the plants receive sufficient light and warmth, they can be placed anywhere. Terrariums look attractive, and if the relationship between the shapes of the container and the plants is taken into account when planting, the glass containers perfectly showcase their inhabitants. The effect is best achieved when you limit yourself to either a single plant, such as an Echeveria elegans, or create a miniature landscape with two or three species. Asparagus setaceus (ornamental asparagus), Nertera granadensis (coral berry), or small cacti are good options for this. Tillandsia species are ideal for a minimalist terrarium because they obtain water and nutrients from the air.
Terrariums also look great in groups. Try similar models in different sizes or a themed collection, such as three or four old apothecary bottles. Whether it's a goldfish bowl or a preserving jar, a lantern or a glass dome: combine as you see fit. The glass containers create a microclimate that's good for plants: moist, warm, and protected from drafts. The glass also makes it easy to study the green inhabitants, and you have a choice of location. They fit well on a desk or dining table, but can also stand on their own as an eye-catcher on a shelf or side table. Terrariums require minimal maintenance. Closed terrariums, in particular, develop their own water cycle. Open terrariums need to be watered occasionally. Otherwise, you should only clean the glass occasionally so the plants are clearly visible.
