Growing notes

  • Flat umbel flowers provide landing platforms for tiny beneficial insects that struggle to land on tubular flowers
  • Ancestor of the cultivated carrot — root is white and woody, not orange and tender
  • Identify carefully — the closely related poison hemlock (Conium maculatum) is deadly and superficially similar, key differences are smooth purple-blotched stems on hemlock and rough hairy stems on wild carrot
