Yellow In Nature

I would not say they are of no use at all. Their seedheads of this particular mix are still fairly good bird food although some of them got petals that are orange to red or red to maroon even, not classic yellow with a somewhat orangey gradient, sparrows and finches still love them.

Well, yes, sunflowers as repacement of nuts in some recipes is a great thing, but effective havesting is somewhat tedious for the elder hobby gardener with athritic fingers. The food sunflower products for people, shelled by machines and processed, are easy available at the grains aisle in any superstore, drugstore or ecomart and I think Renate is more thrilled by all the decorative sorts to grow just for their looks. After all she grows lots of other unfilled asteracae with a different coloured center just for decorative fun too.
