Lilium lancifolium (syn. L. tigrinum) is a species of lily native to northern and eastern Asia, including Japan. It is one of several species of lily to which the common name tiger lily is applied, and is the species most widely known by this name. Like other true lilies, the flowers are borne on an erect stem 80–200 centimetres (31–79 in) tall, clothed with the more or less linear leaves 6–10 centimetres (2.4–3.9 in) long and 1–2 centimetres (0.39–0.79 in) broad. It is one of a very small number of species that produce aerial bulblets, known as bulbils, in the leaf axils along the stem. These can be used to propagate the plant. Flowers on the plant last for a short period of time before they wither and are replaced by newer flowers. It is cultivated in Asia for its edible bulbs. It is also grown as an ornamental plant for its bold flowers, and has become naturalised in parts of North America.
