These plants are commonly found in homes, offices, and various indoor spaces, where they contribute to the ambiance by adding natural beauty and improving air quality. Most houseplants are tropical or semi-tropical species, as they thrive in the warm, humid conditions often found indoors. Many of them are epiphytes (plants that grow on other plants), succulents (which store water in their leaves), or cacti, which are particularly well-suited to indoor environments due to their low maintenance requirements.

==Care== thumb|"Flowers on the Windowsill", 1894 Houseplants have care requirements that differ from plants grown outdoors. Moisture, light, soil mixture, temperature, ventilation, humidity, fertilizers, and potting are all important factors. Each plant species has different care requirements, and care requirements can vary based on the specific pot, location in a particular home and potting mix used. However, all potted plants should have drainage holes to prevent root rot. One way to ensure drainage without a saucer below the pot to catch drippings is by using a "cache pot", which is essentially a larger pot intended to catch excess water, with an interior pot, often made of plastic, as the inner sleeve holding the soil.
