Hemerocallis lilioasphodelus
Hemerocallis lilioasphodelusAlso known as Lemon Lily, Yellow Daylily, Custard Lily
Lemon lilies produce sweet-smelling, trumpet-shaped yellow flowers that bloom sequentially along tall scapes throughout early summer. Individual blossoms open at dawn and wither by nightfall, but mature clumps generate a continuous sequence of fresh blooms for weeks. Native to forest margins and grassy slopes in East Asia, this classic perennial has been cultivated for centuries and served as foundational stock for modern daylily hybrids.

Interaction riskHigh
- Low
- Moderate
- High
- Very high
- Why interaction risk is high
- Highly toxic to cats if ingested; keep domestic pets away and observe safely.
- Why it is dangerous
- Contains toxic compounds that cause acute renal failure in felines, even through small ingested amounts of leaves, petals, or pollen.
- How to recognize a risky encounter
- Look for lemon-yellow, six-petaled trumpet blooms perched on leafless scapes above fountain-like grass foliage.
- What to do
- Do not bring stems into home environments shared with cats, and wash hands after handling the foliage or flowers.
Responsible observation
- Best Viewing Time: Observe in early summer during morning hours when new buds expand.
- Gardening Care: Plant in moist, well-draining soil with full sun to partial shade.
- Pet Safety: Keep cut stems and potted plants away from free-roaming cats.
