How Big Does Fennel Grow

Common fennel can grow up to 6 feet tall but is often shorter than that. The smooth, dark green leaves are finely dissected with very narrow lobes, giving a feathery appearance to the foliage (similar to that of dill). Plants produce a deep, large white tap root.

Does fennel multiply?

Absolutely! When you buy fennel from the store, the bottom of the bulb should have a noticeable base to it – this is where the roots grew from. When you cut up your fennel to cook with, leave this base and just a little bit of the attached bulb intact. Regrowing fennel plants is very easy.
