Do bigger sunflowers have bigger seeds?

Answer:
Yes. Larger members of a cultivar will produce larger seeds. However, different cultivars have different seeds size and shapes. For instance, seeds from a Mammoth Grey Stripe are wider than those from American Giant, even though American Giant can grow several feet taller.
