giant sunflower

ophelia3556August 21, 2010

What variety of sunflower is huge headed and has very black seeds? I have just returned from the state fair and this mystery variety wins every year. I have tried Dianne's mammoth and sunzilla, but cannot get close and they both look very different. Thanks for any help!!

Thank you for reporting this comment. Undo

The biggest heads are typically grown with Dianes strain or Russian Mammoth. It's unusual that a dark black seed is growing very wide. What was the width? I've been growing Dianes and another variety called green goliath with mixed results, 16" - 24" diameter.
