  Tasty foliage with both fish & meat as well as in salads. Fine clouds of feathery, bronze-purple leaves are followed by flat-topped, sulphur-yellow flowerheads in mid to late summer and then by aromatic seeds. This giant fennel looks fantastic as a centrepiece for a sunny herb garden. The foliage acts as a delicate veil through which the flower heads of herbaceous plants and bulbs can be seen.
  
  
• 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.
