Romanesco Heirloom Fennel

Romanesco Heirloom Fennel

Romanesco Fennel is a Florence Fennel heirloom variety—the “bulbing” type of fennel that grows easily and that reliably produces pastel-green oval bulbs and feathery tops. Use the crispy bulbs in a salad, when sliced raw, or you can grill, roast, or sauté them for a juicy, sweet anise flavor to go with other vegetables as a side dish. The feathery and leafy tops can be used as herb seasoning when chopped and spread over some salmon, for example.


  • Grows up to 5 feet tall and 1½ feet across
  • Long, fine, dark-green feathery tops
  • Plant after danger of hard frost is over
  • Likes fertile soil and full sun
  • Can be started from seeds indoors
  • Heavy feeder, so fertilize every 2-3 weeks with high-nitrogen fertilizer
  • Moderate to high-level watering requirements
  • Sweet anise-celery flavor
