Splitlip hempnettle (Galeopsis bifida) is a modest annual herb in the mint family that naturalises easily in partly shaded woodland edges, hedgerows, and disturbed ground. It requires little attention beyond basic watering during dry periods and rewards gardeners with small two-lipped flowers that attract bees. Best used in wildflower or naturalistic garden settings rather than formal borders.
