Translations:Herb/8/en
Ancient Greek philosopher Theophrastus divided the plant world into trees, shrubs, and herbs. Herbs came to be considered in three groups, namely pot herbs (e.g. onions), sweet herbs (e.g. thyme), and salad herbs (e.g. wild celery). During the seventeenth century as selective breeding changed the plants size and flavor away from the wild plant, pot herbs began to be referred to as vegetables as they were no longer considered only suitable for the pot.
