For reliable summer color, you can’t beat Asiatic Lilies. Asiatic Lilies grow easily from bulbs planted in the spring or fall. They require a sunny spot with well-drained soil, but otherwise, are undemanding. Plus, each year these vigorous plants form bigger and better clumps that you can dig and divide to share with friends. Asiatic Lilies grow 24-36 inches tall and make great cut flowers.
