WIKIPEDIA - Liliaceae. General floral formula of the Liliacaeae: Flowers actinomorphic and hermaphrodite with 6 undifferentiated tepals in two whorls of three, the same number and arrangement of stamens, and a superior ovary with 3 fused carpels.
Individual species and genera may have more or less derived formulas. The family evolved approximately 68 million years ago during the Late Cretaceous to Early Paleogene eras. Liliaceae are widely distributed, mainly in temperate regions of the Northern Hemisphere and the flowers are insect pollinated. Many Liliaceae are important ornamental plants, widely grown for their attractive flowers and involved in a major floriculture of cut flowers and dry bulbs.
Some species are poisonous if eaten and can have adverse health effects in humans and household pets. A number of Liliaceae genera are popular cultivated plants in private and public spaces.

Lilium (members of which are true lilies) is a genus of herbaceous flowering plants growing from bulbs, all with large prominent flowers.
Lilies are a group of flowering plants which are important in culture and literature in much of the world. Most species are native to the temperate northern hemisphere, though their range extends into the northern subtropics. Many other plants have "lily" in their common name but are not related to true lilies. Names The term "lily" has in the past been applied to numerous flowering plants, often with only superficial resemblance to the true lily, including lotus, ranunculus, tulip, iris, anemone, agapanthus, zantedeschia, daylily, and others. Range The range of lilies in the Old World extends across much of Europe, across most of Asia to Japan, south to India, and east to Indochina and the Philippines.
Description Lilies are tall perennials ranging in height from 2–6 ft (60–180 cm). Seeds ripen in late summer. Ecology Awards THE LILY FLOWER STORE - Common Lily Diseases.

It's difficult to say just what happened without seeing the bulb before planting and afterwards. There can be many factors involved that created the bulb to die or not produce; planted too shallow, a virus or disease, too wet of soil...So, let's start at the beginning and look at the more common issues.
Oriental and Orienpet lilies are probably the most temperamental to grow. Where to plant is more important than when to plant. Take a little extra time in choosing your location and get to know your soil. The soil should be healthy and well drained. Feeding Virus on Tiger lily Flower Basal Rot Fusarium Damage on Bulb.
