I have had great results with this plant, and with not a ton of special care! Never needs staking, takes the too-sunny spot I planted it in before I knew any better,and has nice fall color right when the flowers are blooming for a neat effect. I will be dividing it this spring,and setting some of the clump into a shadier spot, will see how it does there. Very nice cultivar, and very consistent performer!

A tall aconitum (175 cm) that does 'nt need supporting to stand straight. My friend has it grown in her garden. It flowers in a beautifull amethystblue at the end of summer after a long promiss that starts early spring. Needs a not to sunny spot and dislikes roots.
