Is wild fennel edible?
Definitely use what's in your backyard!
The feathery green bits can be used like a fresh herb in salads or soups.
The tall stalks can become a bed for roasting fish. Another idea linked below for the tender parts.
Collect the pollen when the yellow flowers lose their stickiness and dry it out on a tray. Sprinkle it over salad, chicken, seafood, or infuse its flavor into sauces, ice cream, or panna cotta .
Harvest the seeds when they've dried. They make an excellent rub for porchetta. Infuse some vodka or Everclear with your seeds.
