Once a hallmark of indoor gardening, these terrariums without tops are worth another look for their style and ease. Just pick a theme, pot them, and enjoy.

Some of the most successful (and easiest) houseplants come from the tropics, so it makes sense for beginners to opt for a collection of low-maintenance foliage plants. Fill any watertight container -- in this case, a glass candy dish -- with plants that can tough it out even in the shadiest corners of your house. Add stones or minerals such as quartz as light-catching accents.

A Chinoiserie Garden
In a large Chinese soup bowl, create a miniature hill of potting soil covered in moss, and top it with a woody Chinese elm trained to look like a small, twisted tree. Creeping fig and a variegated fern spill over the edge. You might also add a companion planting, such as this heart fern grown in a ceramic teacup.

Under the Ocean
Strangely shaped plants inspire an undersea garden that may look aquatic but is actually drought-tolerant enough for busy homeowners who might miss a watering or two (or three). Succulents such as spiked aloes, crassulas, and echeverias mimic branchy corals and mix easily with a collection of seashells. A few ceramic starfish on top of the sandy cactus potting mix complete the illusion.

The Orchid Lover
Why isolate each of these prima donnas in separate pots? Instead, combine several orchids in a low pottery planter with ferns and other blooming houseplants. They will love the added moisture they gain being grouped together. Use a well-draining soilless orchid mix, and leave the plants’ aerial roots exposed and not smothered by the top-dressing of moss. (Never overwater orchids since they hate wet feet.)
