Questions tagged [houseplants]

Plants grown indoors. Use this tag with questions about houseplants in general. Please narrow down the scope of the question by using the appropriate genus or common name tags when asking about specific plants.

Houseplants are plants which are growing indoors in pots. They can help to make a room more pleasant, as well as freshen the air by producing oxygen and even to some extent help "clean" the air. Although these effects have been confirmed only in laboratory environment: "Which houseplants should you buy to purify air? None of them"[1]. As well as growing them for decoration, "house plants" could include , (e.g. dwarf citrus), and which are also grown for consumption.

Indoor environments are often very different to outdoor environments in most parts of the world, so the range of practical houseplants are often very different to typical regional outdoor plants.
