Can Fennel and Dill Cross Pollinate?

Gardening forums have been divided on whether the herbs fennel and dill can cross pollinate. This year my garden decided to prove that the warnings are true after all.

I planted my dill in a container right next to the fennel last year. This year, after the dill had died back, new plants began to emerge. I let them grow to see what would develop, and sure enough they weren't dill...and they weren't quite fennel. In fact the foliage colour seemed to indicate that it was a little bit different.

The bottom of each plant has a more fennel bulb look.
The taste is a confusion of both fennel and dill. A bit more fennel but less aniseed.
The texture, however, is far tougher than both fennel and dill which are much more softer.

Having learnt my lesson, I am now growing my dill far away from my fennel plants.

How to prevent cross pollination

  • Plant fennel and dill as far away from each other as practically possible.
  • Since both herbs grow well in pots, moving pots makes controlling their proximity easier.
  • Only plants from the same family can pollinate each other, so the same applies to any other vegetable or flower in the garden.
