Gothic-style illustration of a Hosta plant

Hosta, also known as plantain lily or funkia, is a popular ornamental garden plant. While not technically a lily, this perennial does pose a mild toxicity risk to cats. The leaves, flowers and roots of hosta plants contain toxic glycoside saponins that can cause adverse reactions if ingested by felines.

Hostas are widely cultivated across North America, frequently found in shady garden beds and as potted plants.
