Did you know

  • Sea holly stems and bracts turn an almost metallic electric blue at peak bloom — one of the truest natural blues in the plant world.
  • Despite the name and look, it's not a holly at all — it's a relative of carrots, parsley, and Queen Anne's lace.
  • Candied sea holly roots, called 'eringoes', were a famous Tudor delicacy — Falstaff in Shakespeare's Merry Wives of Windsor calls for them as an aphrodisiac.
  • It thrives in the harshest sand-dune conditions where almost nothing else can survive, anchoring shorelines with deep taproots.
  • The dried flowers hold their color and architectural form indefinitely, making them prized for everlasting bouquets.
