I have a lot of Mexican sunflower seeds from my harvest last fall. Each plant will produce one 4-5-foot-tall stalk with lots of branches that will be full of the beautiful sunflowers. Selling 4 seeds for $1. I have a lot so can get as many as you want. These germinate quickly and yes you will have the flowers this summer and fall if plant now. Picture was taken towards end of last fall when plant was winding down - sorry don't have a better picture. Mt Vernon IL , Salem IL or Odin IL meet
