sylguy, sunflowers originated from seed sown about 5 years ago. The strain was called 'Kong', possibly seed from Burpee. I originally grew them in the far SE corner of lot to provide shade for a couple of Paw Paw trees just planted (as Paw Paw is an understory tree in forest, they need their first 2 or 3 years protected from sun). Growing 10 to 15' tall, they did their job well. They have self-seeded ever since. Interestingly, their densest concentration has migrated to a NW area of garden. I usually just let the seedheads mature where they are. When cleaning garden of debris I might rub a seedhead down and let any seed left fall where they will. When first grown the many flowers included a distinct red component, since then the yellows dominate.
