Fennel varieties and best uses

The conversions above are the same whatever variety you use; the difference is what each is good for. Here is how the common fennel varieties compare.

Variety	Best for
Florence (Romanesco)	Roasting and salads: large round bulb, crisp and sweetly anise-scented.
Zefa Fino	All-purpose: reliable round bulb that resists bolting, good raw or cooked.
Perfection	Braising and slaws: sweet, tender bulb fennel with a mild aniseed flavour.

Which should I pick?

For roasting, braising, and shaving raw into salads, Florence fennel (the round supermarket bulb) is the one to buy: crisp, anise-scented, and widely stocked. No named variety?
