This might not be the difinitive answer, but I had a great crop of sunflower
plants in my deck planters last year that the squirrels had planted. They
got the seeds from the bird feeders. They were 3-5 feet tall and were at
least three different varieties. I now use the "no waste" bird seed, so I'm
going to have to figure out what to do, because I have lousy luck growing
them myself. The squirrels still steal and bury the seeds, but since the
shell has already been removed, I presume they sure won't turn into plants.
And I'll be darned if I can picture in my mind's eye if the sunflower seeds
last year were striped or black oil. If I had to bet, I'd say they planted
the black, because I remember getting a few bags of straight black oil
seeds. The seed MIXES had both kinds.

I don't know what the commercial growers use, but the stuff
you get in 50 lb bags for bird seed will grow just fine. I
won't win any awards with this website, but take a look if
your interested in a few images of Black Oilers.
Last year I had one plant that zoomed to 14 feet (used a
stiff tape measure, no guessing). Most common is about 6-8
feet though. Single or multiple heads.
I to plant 15 to 20 lbs of Southern States black oilers out in a wildlife
plot. One designer seed that I would recommend is the MAximilliam perennial
variety. You got to wait a year for it to bloom but it was worth it, bought
a ounce and dabbled color all around the homestead!
