This swiss chard sprouted itself from last year. It looks lovely but we don't like it so the next door neighbours guinea pig gets it.
This picture is from my garden. When I was growing up we had hundreds of them all down the right side of our garden. During July and August would have our own constant sunshine from the river of yellow. I think they are perennial sunflowers. They would die back in the autumn leaving loads of sticks that me, my sister and friends would use to sword fight.
