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.
Knock Out Roses (Rosa Radrazz) have many worthy attributes, but they will not attract bees to your garden. Although bees visit colorful flowers, it's the pollen and flower nectar that cause them to return to a plant. Knock Out roses are hybridized and do not produce high levels of nectar.
