French Lavender

Lavandula dentata

Also known as Fringed Lavender, Toothed Lavender

French lavender forms compact, aromatic evergreen shrubs distinguished by intricately scalloped or comb-like leaf margins. Throughout warm months, dense flower spikes emerge topped with soft violet sterile bracts that attract diverse pollinators across dry, sunny landscapes. Widely cultivated for its pungent, camphor-laced scent, it thrives in lean soils and tolerates maritime exposure better than many of its close relatives.

Why interaction risk is high
Contains essential oils toxic to dogs and cats if ingested; harmless to touch.
Why it is dangerous
Plant tissues contain linalool and linalyl acetate, which cause gastrointestinal upset, vomiting, and lethargy in dogs, cats, and horses when chewed.
How to recognize a risky encounter
Recognized by its fine, toothed leaf edges, grey-green foliage, and rounded lavender flower spikes capped by delicate purple bracts.
What to do
Keep ornamental plantings or dried cuttings out of reach of curious household pets.
Responsible observation
  • Scent Experience: Gently brush the toothed leaves between your fingers to release the refreshing resinous aroma without damaging the stem.
  • Best Viewing: Inspect the purple spikes in bright midday sun when native bees and flower flies are actively foraging.
