The pictures looked dark pink, maybe leaning towards magenta, not sure!! No, I haven't any and neither has anyone I know. It's the same as pink toads are supposed to be everywhere due to climate change but I only saw the one they showed us at the field centre!
There must be some sort of pink grass somewhere as I don't think it is April 1st, yet. It is snowing quite heavily and laying again here (just north of London), so everything is white just now. Maybe it is another chance for the grass to turn pink!
Do you mean yours? Or in the picture? In the picture, the edges are brickwork. It is pink but doesn't look too authentic, does it? If your grass is anything like mine, it is white again now, and looks as if it will stay like that for a day or two!
