Black Eyed Susie

Question

Why have my Black Eyed Susan plants got empty seed pods? Only one, a dark orange colour, has seed pods at the bottom of the plant, has a very few pods with seeds in of all the other plants. None have any seeds in their seed pods, and there are hundreds of empty seed pods. The plants (orange, red, and primrose yellow) have all grown very well and covered all trellises, a most stunning sight, so why have such healthy plants not got a seed in their pods? Only exception with a few seeds in some lower pods of the orange one, and even that one has masses of empty pods, so what’s going on?

Answer 1

This could be a pollination problem. When there are flowers but no seed production, there may not be enough bees and other pollinators visiting your flowerbeds:
