Definition
Meaning

- Не путать с 'lily' (лилия), это другой род растений.
Common Mistakes
- Misspelling as 'daylilly' or 'day-lily'. 'Daylily' is acceptable; 'day lily' is standard.

FAQ
Frequently Asked Questions
No. They belong to different plant families. Day lilies (Hemerocallis) have grass-like leaves growing from a crown, while true lilies (Lilium) grow from bulbs with stems surrounded by leaves.
Yes, but with caution. The buds, flowers, and young tubers of some species (like Hemerocallis fulva) are edible when cooked. However, some people may have digestive sensitivities, and they can be easily confused with toxic plants. Always consult an expert guide before consuming.
They are low-maintenance. Plant in full sun to partial shade in well-drained soil. Water during dry spells. Divide overcrowded clumps every 3-5 years in early spring or autumn to maintain vigour.
The name comes from Greek: 'hēmera' (day) + 'kalos' (beautiful), meaning 'beautiful for a day', which directly references the short lifespan of each flower.
