Another quickie tonight as it's late (again). Had to catch up with Jonathan Strange & Mr Norrell on BBC iPlayer. It is superb.
This is a plant pictured at the weekend in Somerset but found throughout southern Britain. It is slightly weedlike in behaviour but really a stunning species. Always worth looking out for hummingbird hawkmoths when you find it as they appear particularly drawn to it. It is Centranthus ruber or Red Valerian, and is distinguished from Common Valerian and Marsh Valerian by the spur found at the base of the corolla.
Always a pleasure.
