Pothos (Epipremnum aureum), snake plants (Sansevieria), and ZZ plants (Zamioculcas zamiifolia) are widely considered the best beginner houseplants. They tolerate low light, infrequent watering, and general neglect. Spider plants and peace lilies are also excellent choices, as they visibly droop when thirsty â giving clear signals about when to water.
There is no single watering schedule that works for all plants. The best approach is to check the top inch or two of soil â if it feels dry, it is time to water. Most tropical houseplants prefer to dry out slightly between waterings, while succulents and cacti need even less frequent watering, sometimes only once every two to three weeks. Overwatering is the number one killer of houseplants.
Pet-safe houseplants include spider plants, Boston ferns, prayer plants (Calathea and Maranta), parlor palms, and African violets. Many popular houseplants are toxic to cats and dogs, including pothos, philodendrons, peace lilies, and all true lilies. The ASPCA maintains a comprehensive list of toxic and non-toxic plants for pets that is worth checking before bringing a new plant home.
