Not All Fennel Varieties Form the Bulb Most Gardeners Expect
Fennel, saunf, comes in genuinely different forms depending on the variety: some are grown specifically for the swollen, layered bulb at the base used as a vegetable, while others are bulbless varieties grown purely for their leaves and aromatic seeds, and the two aren't interchangeable despite often being sold under the same general “fennel” label. Growers expecting a bulb from any fennel seed packet are sometimes disappointed to find their plant never forms one, simply because they planted a leaf-and-seed variety rather than a bulbing one. Fennel also has a genuine allelopathic effect on some neighbouring plants, releasing compounds from its roots that can inhibit the growth of certain nearby vegetables, making its placement in a mixed planter worth a bit more thought than most other herbs on this site require.
