Black-Eyed Susan flower Many of us know that it is one of the most beautiful yellow flowers. It has a lot in common with sunflowers. However, sunflowers are slightly larger in shape. I saw a garden by the pond. There were many Black-Eyed Susan trees. The petals of this flower are bright yellow and the parts are black. Among these flowers was a bee. The colors of flowers and bees have a lot in common. All in all a captivating beauty.
