How to Grow Lilies

True lilies (Lilium) are distinct from daylilies (Hemerocallis) — lilies grow from a bulb, produce a single tall stem with flowers at the top, and each flower lasts about a week. Asiatic lilies bloom first (June), are the easiest, and have no fragrance. Oriental lilies bloom last (August), have intoxicating fragrance, and are slightly more demanding. Trumpet lilies fall between in timing, size, and fragrance. Plant bulbs 6 inches deep in fall or early spring. Unlike tulips, lily bulbs are true perennials that return stronger each year and multiply into clumps.

Fall Planting

Lilies are planted in fall, 6 weeks before your average first frost date. Plant 6" deep, 12" apart.

Growing Tips

Plant bulbs in fall or early spring, 6 inches deep. Asiatic lilies bloom first (June), then trumpets (July), then Oriental (August). Unlike tulips, lilies are true perennials that return stronger each year.
