History

Illustrated historical scene for Greater Honeywort

Native to the Mediterranean, Cerinthe major has been grown since antiquity as a nectar-rich forage for honeybees—the genus name derives from Greek keros (wax) and anthos (flower). Pliny the Elder mentioned it in Naturalis Historia as a bee plant. The striking purple-bracted subspecies 'Purpurascens' was collected in Greece and introduced to British gardens in the 1970s through seed exchanges.

Plantsman Christopher Lloyd championed it at Great Dixter in the 1990s, triggering widespread adoption in cottage-style plantings. Unlike many Mediterranean annuals, it self-sows reliably in cool-summer climates.

Today it is valued for its waxy blue-green foliage and pendant tubular flowers in shades from yellow to deep violet. Long known in Mediterranean herb gardens, it was popularized in American horticulture in the 1990s by seed-saver networks and cut-flower farmers. The dusky tones made it a darling of the 'natural' and 'sepia-palette' American cottage garden movement.

Symbolism & meaning

What It Symbolizes

Honeywort is the patron of uniqueness in the spring border — there is genuinely nothing else like its smoky blue-violet bracts cupping inky purple bells. Its quiet beauty rewards gardeners who lean in close: the colors are muted, almost bruised, the kind of palette that reveals itself only on second look. It is for the patient gardener who prizes nuance over splash.

  • Uniqueness — unlike anything else in the spring garden
  • Quiet beauty — muted tones reward closer looking
