Foeniculum vulgare Fennel C DD I?
This common possibly introduced plant is also a culinary herb and well known for its flat headed yellow flowers and feathery leaves. Common both inland and on the coast of southern England, it tends to be found only on the coast further north and is rare in Scotland. At one time it would be grown as a crop but this is hardly ever happens now. In Ireland it is mostly found near the east coast and is rare elsewhere.
