As a comment about Absinthe (Artemisia absinthium)
This is a very strong pungent form of wormwood, used in the making of absinthe. Absinthe spirits were banned in the U.S. and much of Europe in the early 1900s due to their reputedly addictive psychoactive properties. These properties were later found to be exaggerated. A traditional way to prepare absinthe is to place a sugar cube on a slotted spoon over a measure of absinthe, and to pour ice water over the sugar to your taste.
This is one of the more rangy forms of artemisia. Mine grew well over 6' tall in a loose vase form and would have liked about 6' diameter to sprawl. I didn't give it this much thought and it was crowded looking. It would be a very nice background statement in a larger bed, soft greyish leaves.
It did not over-winter for me. I tend to struggle with anything in the artemisia family, I think they like a more alkaline soil and I live in a pretty acidic region.
Listed as a noxious invasive in Washington, Colorado, and North Dakota, so plant responsibly.
