A houseplant is a plant that is grown indoors in places such as
residences and offices, mainly for decorative purposes, but studies have
also shown them to have positive psychological effects. They also help
with indoor air purification, since some species (and the soil-dwelling
microbes associated with them) reduce indoor air pollution by absorbing
volatile organic compounds including
benzene,
formaldehyde, and
trichloroethylene. While generally toxic
to humans, such pollutants are absorbed by the plant and its
soil-dwelling microbes without harm.
Common houseplants are
usually tropical or semi-tropical epiphytes, succulents or cacti.
Houseplants need the correct moisture, light levels, soil mixture,
temperature, and humidity. Without these conditions most house plants
can die easily. As well, houseplants need the proper fertilizer and
correct-sized pots.
