Lilium longiflorum is a stem rooting lily that grows up to 3.3 feet (1 m) tall. It has long, oval leaves, and the vein enters the horizontal direction. The stem is cylindrical and diameter up to 2 inches (5 cm). From April to June, the plant's flowering season, it produces pure white, trumpet-shaped, fragrant, and outward-facing flowers on top of the stem.
USDA hardiness zone 4a to 8b: from −30 °F (−34.4 °C) to 20 °F (−6.7 °C).
How to Grow and Care
Though lilies look like they'd be fussy plants, they are actually very easy to grow. They're not particular about soil type or pH, and they grow well in full sun, part sun, dappled shade, and even light shade.
Plant lilies as soon as you get them, either in the fall or the spring. Because the bulbs lack the papery covering (known as a "tunic") that is common to other hardy bulbs, they can dry out quickly in storage.
Even more than other bulbs, lilies demand well-drained soil. Dig the spot where you plan to plant lilies to a depth of at least 12 inches (30 cm), remove rocks and add organic matter, such as leaf mold or peat moss, to improve both the soil's structure and drainage. Like other bulbs, lilies appreciate a little bone meal scratched in at the bottom of the planting hole, but do not really require other fertilizers at planting time. Instead, wait until the bulbs send up green leaves and then sprinkle a complete organic fertilizer around the plant and water it in. See more at How to Grow and Care for Lilies.
It is endemic to Japan (Ryukyu Islands).
