Yes, Lancifolium Splendens lilies, also known as Tiger Lilies, typically come back every year. These perennial plants have a bulb that remains in the ground during winter, and then regrows in the spring. They are hardy in USDA climate zones 3-9.
With proper care and maintenance, they can continue to bloom for several years. However, like all plants, their lifespan can vary depending on factors such as soil quality, water, and sunlight. It's important to note that while Lancifolium Splendens lilies are hardy and can tolerate a variety of growing conditions, they may not survive extreme temperatures or weather events.
