This is a striking plant when in flower, however it has yet to flower in Ontario that I know of. That said it is well worth growing as a herbaceous plant for its striking, coarsely dentate foliage. Professor Jim Phipps, from the University of Western Ontario and living north of London, Ontario has a large specimen in his garden. We hope to have one in the A. M. Cuddy Garden in the near future.
