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.

Aconitum napellus 'Newry Blue' has deep, indigo coloured flowers held closely together to form a denser spire than the uncultivated species. It usually flowers in June and July.

For best results, grow Aconitum napellus 'Newry Blue' in full sun or partial shade, in moist, well-drained soil. Light soils should be improved with lots of well-rotted organic matter before planting. Find out more in our Aconitum grow guide.
