My Sunflower seems to have 15 heads!

[MummyBtothree]

This is the first year we have grown quite a few sunflowers and one of them seems to have 15 heads in total on it. They are coming everywhere off the main stem. Is this quite common? .

I think it depends on the variety.

I think I picked the seeds out of the bird seed :)

I love the bird seed Sunflowers, they pop up everywhere and surprise me!
