Hosta is a genus of herbaceous perennial plants that belongs to the family Asparagaceae. They are commonly known as "plantain lilies" or "funkias" and are prized for their attractive foliage. Hosta plants are native to East Asia and are now grown in many other parts of the world as ornamental plants.

Hosta plants have low-growing stems that produce leaves that can be green, blue, yellow, or variegated, and can be quite large and showy. The foliage of Hosta plants is often heart-shaped or oval, and can be quite textural.
