Eupatorium cannabinum. A beautiful tall, pink plant that forms large stands. It is in flower now.
No. Sorry it is a member of the Daisy family. It only got the name Hemp because the leaves resemble those of the Cannabis genus of plants (in shape)
I don’t know how it came by the Agrimony part of it’s name. Agrimony is a member of the Rose family and doesn’t bear any resemblance to this plant. The name Agrimony is derived from a Greek word Argemone meaning healing to the eyes, while in herbalism this plant is used to treat swollen feet. You can’t get much further from the eyes than that 🙂
