Christopher Bradley-Hole used this to great effect in his 2013 garden at the Chelsea Flower Show. It is a hardy perennial, with attractively divided foliage, from which dark-stained stems arise bearing pretty umbels of pink-tinged, white flowers in midsummer. These are particularly attractive to pollinating insects. Allow it drift through naturalised planting schemes, prairies and woodland edges.
- Garden care: 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 them cut back to 30cm from the ground.
