Tell me the sunflower seeds sold as bird seed in the pet shops can/do they germinate?
Last year I bought a 10 lb bag of the "Oil Sunflower Seeds" sold in the bird feeder section of Home Depot. Many germinated below the bird feeder like weeds. The birrds must have carried others off and dropped them, as they sprang up more than 10 feet from the feeder. I let a few flower and the shape of the plant and the flower were more like the native sunflowers that grow along the roadway here - not like the giant ones you plant in the garden.
