What Exactly Are Tiger Lilies?
This same common name is often used for totally different plants.
The facts below pertain to what plant taxonomists have classified as Lillium lancifolium (alternate botanical name, Lillium tigrinum). The genus name indicates it is a true lily, not a daylily such as Stella de Oro.
Botanically speaking, these are herbaceous perennials that grow from bulbs. Gardeners generally plant the bulbs in spring. They are summer-flowering bulb plants, unlike daffodil, tulips, etc., which are spring flowering bulb plants.
Indigenous to the Far East, tiger lily plants can be grown in planting zones 3 to 9. Like many flowers, they prefer to be grown in a sunny location with well-drained soil. However, these tough specimens are not nearly as fussy about growing conditions as are many plants; for example, they will tolerate partial shade. Tiger lilies have just average water needs.
