I adore sunflowers. And butterflies! :)
If you plant the little black oil ones, the ones most people use to feed birds, they make the loveliest sunflowers. They only get about 4’ tall and the flowers are about saucer or breadplate size, but they smell heavenly! Sometimes you get a sunflower bush, with blooms all over it. They only take about 6 weeks from seed to bloom. If you plant them every 2 weeks or so, you’ll have sunflowers all summer!
My daughter has great “volunteers” from the birdfeeder spillage..I have some spindly ones come up..but I just don’t have enough sun to get the big ones.
