orange day-lily
Hemerocallis fulvaAlso known as Tawny Daylily, Ditch Lily, Tiger Daylily, Corn Lily
Orange day-lilies form dense, expanding clumps along roadsides and garden borders through vigorous underground rhizomes. Each fiery trumpet-shaped flower opens at dawn and fades by dusk, replaced the following morning by a fresh bud on the same tall stalk. Native to eastern Asia, this hardy perennial thrives in poor soil and dry conditions, often outcompeting native vegetation in naturalized areas.

Interaction riskHigh
- Low
- Moderate
- High
- Very high
- Why interaction risk is high
- Highly toxic to cats if ingested and can cause stomach upset in humans; keep away from pets.
- Why it is dangerous
- Contains toxins that cause fatal acute kidney failure in cats, while human consumption of raw plant parts causes stomach upset.
- How to recognize a risky encounter
- Look for orange trumpet blooms with wavy margins, six curved stamens, and arching sword-like leaves arising from tubers.
- What to do
- Keep all plant parts away from cats, and never consume wild blooms without verifying identification and proper preparation.
Responsible observation
- Garden Placement: Plant in full sun to partial shade in well-drained soil to support robust summer blooms.
- Pet Safety: Ensure patches remain inaccessible to curious domestic cats, as all parts cause renal damage.
- Spread Control: Dig up expanding tubers or remove spent blooms to prevent aggressive spread into natural areas.
