Despite its name, lucky bamboo (Dracaena sanderiana) isn’t actually bamboo at all. Rather, it’s a decorative houseplant known for its near indestructibility. These plants can thrive in soil, but most gardeners choose to grow them hydroponically. All you need is a glass of water at least an inch deep and a support system of gravel (or some other medium) to keep the plants standing straight. Available on Amazon; $12.99 for 38 stalks.
An adaptable houseplant, philodendron is recognized by its lush, trailing, heart-shaped leaves. It tolerates both low and bright light, and requires very little care. While the plant is usually grown in a pot, it is a plant that can flourish without soil and will grow just as easily in a jar of tap water. To propagate philodendron this way, simply snip off about six inches of an existing plant and remove the two lower sets of leaves. Submerge the cutting in a glass or jar of water, and wait about 10 days until you see roots forming at those leaf nodes. Available on Amazon; $4.50 for a four-inch pot.
Most tropical orchids are epiphytes, meaning they grow on other plants instead of in soil. But orchids and other epiphytes aren’t parasitic; their roots are covered in a squishy membrane that sucks up water from the atmosphere. Many orchids sold as houseplants come in a planting medium, such as moss or stones, but they will grow just as easily on a piece of bark once their roots take hold. Available on Amazon; $24.99 for a double-stem plant.
Air Plants (Tillandsias)
Members of the genus Tillandsia, air plants are exactly what they sound like: plants that grow in air instead of soil. More than 650 varieties exist, displaying an immense variety of foliage and colorful blooms. The leaves of air plants grow in a rosette formation, which helps the plants gather water and nutrients from the environment. When displayed as houseplants, they're typically placed in decorative dishes or mounted. Available on Amazon; $18.95 for a 12-plant variety pack.

With its drooping, gray-green tendrils, Spanish moss (Tillandsia usneoides) evokes humid summer days and the romance of southern climes. The plant often grows from trees, absorbing water and nutrients from the atmosphere, but with proper care it can also grow indoors. To maintain Spanish moss as a houseplant, mist it with water at least twice a week and fertilize it with high-phosphorus liquid fertilizer every two weeks. Any Spanish moss gathered from the wild will be infested with small insects, so if you want to grow it indoors, purchase plants from a trusted supplier. Available on Amazon; $13 for a one-gallon bag.
Marimo Moss Balls
Marimo moss balls, also known as Cladophora balls, are spherical algae. They can be grown in an aquarium with fish, or they can live alone in a jar of water. To maintain marimo moss balls, simply keep them in low indirect sunlight, and change their water every couple of weeks. Available on Amazon; $13.95 for 10 balls.
Paperwhites (Narcissus tazetta)
Paperwhites are a variety of daffodil that can be forced from bulbs indoors during the winter. These fragrant plants will gladly grow in nothing more than water and some pebbles. Thanks to their white and yellow blooms, cheerful paperwhites will buoy you up over those cold, gray months. Available on Amazon; $23.40 for five bulbs.
