Cow Parsley or Queen Anne’s Lace, the hedge banks are graced by a frothy display of this natural traffic-calming measure. In my view always there for too short a time before Highway’s Authority tidiness means that it has to be cut to allow cars to speed through the lanes with impunity. In the mean time the natural display set off with the blue of Germander Speedwell (what an apt name) is better than artificial set that Chelsea has to offer.
