I am not sure why……but they are much bigger than everyone elses and I didn’t feed them. I put it down to chicken poo…….I tried to take some photos today but the sun was in the way, in the end I got this one…its slightly on the turn, but if I tell you I am standing underneath it it will give you some idea. I like sunflowers, they are such cheerful plants, and very useful. When I put the seeds in I put them in the same time as some dwarf ones and forgot they needed to grow so tall. As a result they were late out but the bees have been busily working them, they are great pollen plants. Last time I tried feeding some of the seed heads to my chickens. John Seymour said you could just chuck them the head and they would pick at it, his were obviously more intelligent than mine. They hadnt a clue,they looked at them as if they had come from outer space. They do enjoy some fruit from the trees though and like raspberries when they can get their hands (or feet?) on them..
