The weather can be glorious in late summer but the garden can start to look tired this time of year if not properly planned and planted. But as the daylilies start to look emaciated, this humble stunner bursts on the scene. Standing just 12″ tall, Aconitum cammarum “Blue Lagoon” is a potent way to reinvigorate your garden’s color in time for the start of school. Those with dogs or culinarily intrepid children should we warned that this plant, like all monkshoods, is toxic if consumed. But for those who refrain from eating it can glory in its beauty for much of the fall. Grows well in sun to half shade and is deer resistant.
