Most of the seeds are still there somewhere, just fallen off/outta the head. Have been told by more than one biologist that the seeds from that variety are actually harder for birds to digest due to some sort of coating that it naturally has. I've tried a lot of things to try to get the annual(big pink bloom) to grow year after year. But, have not had any huge success stories yet. Some good scattered stands here and there, but not the results Im looking for. And if I have to plant every year...why not plant millet, rice, and milo?
