This is Max’s Echium candicans. To my knowledge it has eaten one persicaria, one cistus and a salvia and is well on its way to consuming an evergreen azalea. Come to think of it, I haven’t seen next door’s chihuahua for a while ……..
This Pride of Madeira has grown into a monster in just four years, from a small cutting acquired (legitimately, before you ask) from a friend’s garden just up the road. It is spectacular and scary in equal measure, and is of course extremely attractive to both human and pollinator. A humming monument.
