In the design
Birds will take the seed. That's fine. Not the same plant as native perennial sunflowers.
If you eat it
Seed, roasted, if you beat the birds
Eat roasted seed only. Don't assume every sunflower relative is a snack.
Only eat what you planted and can name. This is not a foraging or medical guide.
