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.
The more color and the wider variety of flowers in your garden, the better. They are particularly fond of blue, purple, yellow, and white flowers. Use Native Plants - Bees in your area will be most attracted to native plants that they are familiar with. Mix a few in with your favorite ornamentals.
