Pothos
Snake Plant
The snake plant is more or less indestructible. Root rot, which comes from overwatering, is the only problem you might encounter with a snake plant. It comes in tall forms as well as shorter forms that look more like a bird's nest.

Kalanchoe
With colorful flowers that can last several months, kalanchoe brings a bright touch to any indoor space. It does well in low humidity and lots of light, and blooms during the short winter days.

Cast-Iron Plant
Another hardy option, the cast-iron plant can deal with both lack of water and lack of light. The perennial tends to grow slowly and can withstand all different temperatures. Some types have cream or yellow variegation on the leaves, but these tend to be a bit more delicate than the normal dark green variety.

English Ivy
English ivy is often grown outdoors as a ground cover, but also works well inside. Though it will grow slowly in the first year or so after you plant it, by the end of year two it'll climb and cover almost any surface. Be careful if you have small children or pets—all parts of English ivy are poisonous, so you should keep them up high and out of reach.

Spider Plant
The spider plant comes in a huge range of varieties, and all work well as hanging plants. It takes its name from the "spiderettes" that grow off of the main plant and resemble—you guessed it—spiders. You might notice the tips of its leaves turning brown, which likely comes from fluoride in the water and shouldn't cause concern. Leaching the plant (giving it a thorough watering) can help.

Rubber Tree
Named for its sticky and plentiful sap, the rubber tree is a dramatic option that can grow extremely tall. It needs full to part sun, and shouldn't be kept in a room that gets direct sunlight all day long. The rubber plant loves watering and moisture, though yellow or wilted leaves are a sign that you've gone a bit too far.
