My DS grew a sunflower at nursery that we then planted in our garden and it has grown to just over 10ft
DS loves it and I want to harvest the seeds, but I'm not sure when?! The sunflower has completely drooped over now, and the floret things brush away really easily, revealing the seeds underneath, but they are still white, which is confusing me as sunflower seeds are usually black/grey aren't they? They are massive and really plump, so do I leave them even though the plant is dying, or do I harvest them now? Will they change colour?
Thanks in advance, my gardening knowledge is severely limited, and google isn't my friend today!
