Bell heather is our most familiar heather. In summer, it carpets our heaths, woods and coasts with purple-pink flowers that attract all kinds of nectar-loving insects.

Wild carrot does, indeed, smell of carrots, but the roots are not like our cultivated, dinnertime favourite. Look for this umbellifer on chalk grasslands and coasts.

The delightful fragrance of wild thyme can punctuate a summer walk over a chalk grassland. It forms low-growing mats with dense clusters of purple-pink flowers.

Wild privet is a shrub of hedgerows, woodlands and scrub, but is also a popular garden-hedge plant. It has white flowers in summer and matt-black berries in winter that are very poisonous.

Wild marjoram is actually the same aromatic herb as oregano which is used in Mediterranean cooking. Its small, pink flower clusters can be seen on chalk and limestone grasslands in summer.
