Single petal zinnias
Hi! I’m in 6b and have a zinnia question. After falling in love with zinnias several years ago I decide to add some of the “fancy” varieties to my garden. I spent a fair amount of money on several zinderella and Benary seeds. The vast majority of them haven’t even bloomed but the few that have looked absolutely nothing like the photos. They are sort of wonky single petal zinnias.
I also bought (from very reputable seed growers) some of the mixes (raspberry sorbet, key lime, bridal) that are all supposed to be fully double. While most of those are blooming they are all just single petal.
Then on the other hand my cheap Walmart purple prince and Oklahoma and queeny seeds are thriving ! So I don’t think it’s my soil or conditions. Any advice?
