Well I'm sure these cosmos didn't have aster yellows. But before I go any further, I'll take pictures of the cupcakes tomorrow. They're not blooming yet and they're going to look lonely compared to these. I did buy a lot of Cosmos seeds this year but I didn't get many started. If I can find some old pictures of those tall closely planted Cosmos, I'll post them here. The stems were huge by the end of the season.
