Lilium lancifolium

Tiger lily is an herbaceous perennial member of the lily family (Liliaceae). It is classified in the Asiatic Lily group. It is native to far eastern Russia, Tibet, China, the Korean Peninsula and Japan but has escaped and naturalized in many parts of the world, including eastern North America. The species epithet is Latin meaning “lance-shaped leaves” and describes the leaf shape.

Tiger lily is one of the easiest species to grow… and one of the hardest to contain within its allotted space in the garden. It thrives in full sun on moist, acidic soil. In shadier conditions, it will survive but flower production will be poor. The plants produce bulbils–one in every leaf axil–that drop to the ground and grow. They are the easiest way to propagate this species, but they can also allow this species to spread aggressively in the border.

This species is believed to be a sterile triploid throughout much of its introduced range, suggesting that the plants throughout eastern North America are genetically identical clones. Tiger lilies do not produce fruits or seeds, nor are they used in breeding programs. The flowers are colorful but not fragrant.

Tiger lily can be used in butterfly gardens, children’s gardens or Asian gardens. It can also be used for cutting. Grow this species in the border or in containers, but be warned: this species spreads. Consider using other lilies, such as the Asiatic Hybrids, that do not produce bulbils.

Insects, Diseases, and Other Plant Problems: This species spreads asexually and can become weedy.
