Lilium davidii var.
willmottiae
This photo depicts a curious characteristic in some species lilies. Rather than the stem arising from the bulb, and continuing straight upward to the soil surface, it decides to meander diagonally before it reaches the sun. Sometimes stems even travel horizontally. Bulblets are produced along the stem in some species like this one. These are different from the rhizomatous types of lily bulbs, whose underground stems are perennial. These, like
Lilium davidii shown here, are annual stems, that last only during the growing season.
