What does a fennel plant look like

Fennel has a round bulb that grows underground with a long, green, feathery top sticking straight up high out of the soil. The feathery leaves that resemble dill, can also be used as a herb garnish.

Among the leaves are small yellow flowers and this is where the fennel seeds are produced. Every part of the plant is edible, from the bulb, feathery leaves, flowers and of course the seeds.

How do you get seeds from fennel?

During the late summer / early autumn season when the fennel plant reaches the end of the blooming cycle, the small yellow sprouting flower head turn brown.

The heads are then cut away from the plant and left to completely dry. Once they are fully dry, the seeds are easily shaken loose from the stem.
