I'm collecting seeds from Mexican Sunflower. Some of the seeds are brown, some are black. Are they all viable? I don't remember what color the original seeds were that I planted.

Hi Ponder,
I checked mine and they are brown with darker speckles. It is possible they turn darker with age. I wouldn't be too concerned about color. They need to be plump and hard. Ones that didn't fertilize correctly will be flat and flimsy.

Thanks. They are all plump. It surprised me that they look so different.

I picked my first seed head on Monday. I have different shades on mine.

Bump...So how do I know when the seed head is ready to cut off? I've searched google and had no luck. Does anyone have pictures from flower to harvest? Thanks in advance.

Most seeds are ready when you can run your thumb across the head and a few seeds start falling out from the head. But they still need to dry more before storage.
