Here it is, the penultimate flower to bloom here. I like this Aconitum because it blooms so late, adding a dark blue-purple to the Autumn garden. I got it at a local garden club sale, but the lady who sold it to me didn't know which species of Aconitum it was.
It stands tall and fairly straight in the main woodland garden, but leans horribly in the raised bed by the house. (I should pair it with Anemone 'Party Dress' for a drunken plant effect.)
It also has a problem of stem die-back. I cut out the dead stems, and there are usually enough healthy stems left.
I think it is worth growing anyway for the beauty of the flower.
But the best thing about Monkshood is that it is very poisonous. Feel lucky, rabbit, do you? Go ahead, make my day.
