It is said that cow parsley is one of those plants which is taking over our hedgerows. Perhaps so but it is one of those plants which with its delicate ,lace like white flowers brings colour to our country roads and announces that we have passed from Spring to Summer. It is joined in this message by the hawthorn blossom. Both plants line my route home. What passes for Northern Ireland's summer has arrived, - at last. Another five days and the evenings will start to draw in!
