If you want to attract bees to your garden to pollinate your vegetable and fruit flowers you need to have plenty of flowers that bees like to draw them to your garden.
From my experience, I have some favorite flowers that you will not only enjoy but you will attract bees, butterflies, and birds to pollinate your garden.
One of my go-to flowers to attract bees is the Zinnia, which comes in a multitude of colors and sizes.
