Eupatorium cannabinum L. (Hemp Agrimony)

Wildlife Gardening An excellent large plant to the wildlife garden, but can be invasive and it may be better not to let it seed.

If planted in full sunshine, it is most attractive to bees, hoverflies, and many other insects.

To reduce the height, disturb the plants in early spring (eg Feb) by digging them up and replanting in the same hole.
