|Lilium carniolicum var. albanicum has leaves that are hairless beneath, and bears plain yellow flowers. N.Greece, Albania.
There are approximately 100 species of lilies. A bulbous perennial, that originated in wooded areas of Europe and Asia, the lily has become a favorite in gardens across the world noted for its trumpet-shaped flowers. Depending on the species, bloom time ranges from spring to fall. All lilies will prefer a well-drained location with rotted organic matter. Lilies require a cold period, so it is uncommon to find plants that thrive in zones 9-10. While most lilies prefer acidic soil, there are a few that do best in limey soils. Spring and fall are the best time to transplant, even though they can be transplanted any time. Provide ample moisture while flowering, but can take periods of drought otherwise.
