Lilli is a genus of herbaceous flowering plants growing from bulbs. Most species are native to the temperate northern hemisphere, though the range extends into the northern subtropics. They comprise a genus of about 110 species in the lily family (Liliaceae).
Lilies form an important group of flowering garden plants, and are important culturally and in literature in much of the world. Some species are sometimes grown or harvested for the edible bulbs.
