My father-in-law received these lilies as a gift- I don't know the name, but the plants grow up to 48 inches tall and have many blooms as shown in the photos. They bloom in July.
Asiatic lilies are fairly easy to sprout.
Sow seed in potting soil that has been pre-moistened, 1 inch apart (2.5 cm.) with a fine dust of ½ inch (1 cm.) of soil over them. Pat the soil onto the seed gently. Within four to six weeks, seeds should sprout. Keep them lightly moist and give young plants 14 hours of light per day. Every 14 days, feed with liquid fertilizer diluted by half. When seedlings become dormant, repot them into slightly larger containers to grow on.
How to Plant, Grow, and Care for Lilies
With colorful, star-shaped flowers, lilies give star power to summer gardens. Lilies add graceful elegance and fragrance to any garden, blooming from early summer all the way through fall, depending on the type. At home in both formal and naturalistic settings, most lilies also take readily to containers. Plus, they make great cut flowers!
Lilies have six plain or strikingly marked tepals (“petals”) and are often trumpet-shaped, sitting atop a tall, erect stem with narrow, long, lance-shaped leaves.
