Camellia plants, including Camellia sinensis (tea) and popular ornamental landscape varieties (Camellia japonica), are widely considered safe, non-toxic to humans, and non-toxic to domestic household pets such as dogs, cats, and horses according to organizations like the ASPCA. The leaves and blossoms do not contain dangerous systemic toxins, making them safe to cultivate in residential gardens, though consuming large quantities of unfamiliar garden plant matter is generally discouraged.
