Fennel, a hardy, perennial, umbelliferous herb, with yellow flowers and feathery leaves, grows wild in most parts of temperate Europe, but is generally considered indigenous to the shores of the Mediterranean, whence it spreads eastwards to India. It has followed civilization, especially where Italians have colonized, and may be found growing wild in many parts of the world upon dry soils near the sea-coast and upon river-banks. It flourishes particularly on limestone soils and is now naturalized in some parts of this country, being found from North Wales southward and eastward to Kent, being most frequent in Devon and Cornwall and on chalk cliffs near the sea. It is often found in chalky districts inland in a semi-wild state.
Fennel will thrive anywhere, and a plantation will last for years. It is easily propagated by seeds, sown early in April in ordinary soil. It likes plenty of sun and is adapted to dry and sunny situations, not needing heavily manure ground, though it will yield more on rich stiff soil. From 4 1/2 to 5 lb. of seed are sown per acre, either in drills, 15 inches apart, lightly, just covered with soil and the plants afterwards thinned to a similar distance, or sewn thinly in a bed and transplanted when large enough. The fruit is heavy and a crop of 15 cwt. per acre is an average yield.
