Largeflower False Rosemary

Conradina grandiflora

Also known as Large-flowered Rosemary, Large-flowered False Rosemary

Largeflower false rosemary is an aromatic, woody shrub endemic to the ancient sandy dunes of eastern and central Florida. Pale lavender to blue two-lipped blossoms speckled with dark purple spots burst open across its needle-like foliage primarily from late winter through spring. Highly adapted to fire-maintained Florida scrub, it relies on open sunny clearings and releases a pungent piney fragrance when its resinous leaves are disturbed.

What to notice
Look for a sprawling woody shrub with slender needle-like leaves and distinctly large, two-lipped lavender flowers dotted with purple in the throat.
Support conservation
Never dig, prune, or collect wild specimens; observe plants from official boardwalks and sand trails to prevent soil compaction.
Responsible observation
  • Crush-free aroma check: Gently stroke the needle-like foliage with your fingertips to release its rosemary-like scent without harming the plant.
  • Stay on established paths: Florida scrub soils are easily degraded and host fragile biological crusts that support these root systems.
  • Look for solitary bees: Watch the violet flowers during sunny midday hours to spot native bees gathering nectar from the lower lip.
