A herb garden is a favorite way of assembling herb plug plants and examples can be seen in many Botanical gardens and at Historical houses throughout the British Isles.
Mostly, the average gardener only grows the herb varieties he or she likes for their own consumption or decoration.
Herb plug plants fall mostly into two distinctive groups, culinary and aromatic, although as in most things there are the exceptions to the rule, one that comes to mind is the Lavender, this is usually used for its perfume but can be used to flavor scones, cakes etc.
The foliage of herbs are used both in the 'green' state and dried, incorporated into food or just sprinkled over dished.
Some of the more popular types of herbs are Sage, Thyme, Rosemary, Garlic, Mint, Coriander, Balm, Oregano, Feverfew and of course Lavender.
