Fine clouds of feathery, bright green leaves, which have a sweet aniseed flavour are crowned with flat-topped, sulphur-yellow flower heads in mid- to late summer, followed by aromatic seeds. Fennel is the perfect centre-piece for a sunny herb garden. An invaluable border plant, the foliage provides a delicate foil against which the flowers of herbaceous plants and bulbs can be seen.
How to care for Foeniculum vulgare:
The plant's tendency to self-seed may be a problem in hot summers. If fennel is being grown exclusively for its foliage, remove the yellow flowerheads to prevent it from self-seeding. When flowers have finished cut back to 30cm from the ground.
