Have you ever grown sunflower??

No I haven't yet but my mother had done this and it was very successful. Everyone was stopping by to have a look those giant beautiful flowers.

Yes, I have but I am not very successful with them. The more sunflower seeds I plant, the more the dogs eat and break them. Usually from twenty I plant only one or two make it and they do not grow well, they stay about four feet small and they never get ripe. It seems to be either dogs or sunflowers.

I have never purposely planted them. The birds plant them for me by dropping seeds. I think 3 feet is the tallest mine have ever gotten. They're so pretty, and the birds eat the seeds out of them once they start to go by. Your 10 feet ones must be gorgeous!
