Dwarf Larkspur

Delphinium tricorne

Also known as Spring Larkspur, Rock Larkspur

Dwarf larkspur emerges early each spring on rich forest floors, producing striking racemes of deep blue to violet spurred blossoms before the canopy fully closes. Its deeply lobed leaves wither away by midsummer as the plant returns to underground tubers for seasonal dormancy. Every part of this wildflower contains neurotoxic diterpene alkaloids that deter most grazing mammals.

  4. Very high
Why interaction risk is high
Contains toxic diterpene alkaloids; do not ingest and keep away from livestock and domestic pets.
Why it is dangerous
Contains potent norditerpenoid alkaloids that disrupt neuromuscular signaling, causing severe gastrointestinal distress, muscle spasms, and cardiac toxicity if ingested.
How to recognize a risky encounter
Look for palmately lobed leaves and short stems bearing deep blue-purple flowers with distinctive nectar spurs in early spring.
What to do
Avoid picking or chewing any part of the plant, and keep curious pets and children away.
Responsible observation
  • Optimal timing: Search rich mesic forests in early spring when flowers actively bloom prior to forest canopy closure.
  • Habitat cues: Look along limestone bluffs, nutrient-rich slopes, and moist ravine bottoms.
