Aconitum napellus – also known as monkshood, wolfsbane and aconite – is plant steeped in lore because of the toxin, aconitine, it contains. It’s a beautiful herbaceous perennial with finely divided leaves similar to those of delphiniums, to which it’s related. It bears deep purple-blue flowers held on spires a metre or so in height and enjoys growing in cool, moist soil. It usually flowers in June and July.
