Delicate, sweet-flavored fennel bulb is one of routnely found vegetable ingredients featuring in the Mediterranean cuisine. Its succulent enlarged bulb imparts special “anise” like sweet flavor to the recipes. Bulb fennel is cultivated for its beautiful, squatted stems in many regions of the southern Europe, especially in Italy. It is also known as Florence fennel, finocchio, sweet fennel, etc.
Bulb fennel is a cool season perennial herb but grown as annual vegetable crop. Unlike seed fennel, bulb fennel is a small herb growing up to only 2 feet in height. As the plant grows, its thickened lower leaves overlap one above the other to form into a swollen, bulb-like structure just above the ground. At maturity, its bulb measures about 3-5 inches in width and about 3 inches in length.
As the plant grows, oftentimes, surrounding soil is pulled around the stem base to create a mound to obtain long blanched fronds.
