hi all, im astonished and somewhat confused. I decided this year to have some fun in my garden and took a handful of sunflower seeds from my parrots food and scattered them randomly in the garden, mainly for my grandchildren to watch grow. well we had a stunning array of flowers and still do have some coming up, but, and i say but, we have one in the corner of the garden, it has at least 15 stems and this morning i have counted 50+ closed buds + 1 open flower which is the colour of an evening sun going down, im astonished, is this normal and if so will the seeds from this one plant raise others. i have never seen anything like it!!!!! please help
