The fall blue monkshood is fairly common in gardens, but very few people have ever seen a climbing monkshood. Aconitum alboviolaceum is such a plant – and a stunning plant at that. This is a rare species that I obtained from Botanically Inclinded and planted last year, as a good sized plant. Normally in this column, I only write about plants that I have grown for a couple of years so that I know they are perfectly hardy in zone 5, but I am making an exception for this very special plant which has grown in Waterloo, Ontario for a couple of years.
