If space is at a premium, but you don't want to compromise on colour, then  this new catmint could be just the ticket. It forms a compact clump of aromatic foliage, which is topped in summer with upright spires of larger than average  Neptune blue flowers. It's a little plant, but it will really pack a punch in   pots or front of border positions.
                                    
                                        How to care for Nepeta Neptune ('Bokratune') (PBR):
                                         If cut back after the initial flowers have faded, this nepeta will usually go on to produce more. Lift and divide large clumps in spring, replanting divided specimens with lots of well-rotted organic matter. If powdery mildew becomes a problem prune out the affected areas.
