Bees see the world much differently than people do. A small cluster of tomato blossoms won't catch their attention, but a lawn peppered with clover and dandelions sends then into a pollinating frenzy. If you're serious about attracting bees to your vegetable garden, plant flowers.
Greek beekeepers move their hives from one place to another depending on the season, so that the bees can feed on various, specific flowering plants, such as thyme, heather, chestnut blossoms, pine, orange blossoms, etc. That is why we have specific honey varieties, such as thyme, pine, etc.
