No. I thoroughly studied the Jerusalem Artichokes and the other choke which is “Sun Chokes” thinking that might work, too, but they have little to no oil and very few seeds. The flowers have thin petals and the flowers aren't big. They are just grown for the everlasting tubers, not for oil and not for eating.
The “Black Oil” Sunflower is the one for getting oil from the black seeds.
The “Sunspot” Sunflower grows only to 2 or 2 1/2 ft., has 10 inch flowers and is packed with striped seed which is the one for eating. These are the ones I just grew from seed and will plant soon within the next few days. I'm gong to try growing them in grow bags. They are not perennial like the Jerusalem and Sun Choke ones.
Thanks Marcella! I knew you probably had unearthed whatever there was to be had on the subject!
I grew some Mammoth ones last year and they were awesome. They produced the kind of seeds that you can eat - gray striped. I’ll need to look into getting the “Black Oil” Sunflower for next year, as well as the “Sunspot.”
