Hello.. This year I planted thousands of wildflower seeds in my yard. I took out my grass, for the majority of my back yard lawn, and mixed in compost and wildflower seeds. I used a pre-mixed variety of annuals, biennials and perennials. Most of them are between 4-14" now. depending on the type. I have no clue what is what.. About 1/16th of them have flower buds already, and the first one just flowered today. I am hoping someone knows what it is.. I have about 20 of them growing, this is just the first to flower. It seems that it will have multiple flowers on the top.. as there is buds next to the bloom. The plant itself is about 12-14" tall and the flower is about the size of a half a penny. If it isn't a wildflower, perhaps it is a veggie seed that blew from my veggie garden?? Any ideas? Thanks in advance, I appreciate your help!!
