Hi Elvis,
Well coneflower(Echinacea) seeds are always the same shape. The color and size may vary depending on the coneflower, but you can always tell they are coneflower seeds. People that don't know much about seeds often mess up and send the coneflower chaff around the seeds thinking that is the seeds instead of the seeds themselves. So that can be a possibility if your seeds don't look like coneflower seeds.
I can't figure out what wirral is suppose to be. I googled it. Is it a shasta daisy cultivar? If so, shasta daisy seeds look like little sticks.
Hopes this helps,
Remy
