Wormwood
Did you ever wonder what the plant they make absinthe out of looks like? Artemisia absinthium looks like this!
And you can grow it if you want. Shrubby to 3 or 4 feet tall, and easy to propagate from cuttings in the spring, it also doesn’t need to be watered very often. Now that’s service!
Now they tell me that if you extract the oils, wormwood can get very poisonous, and yet people use the dried leaves as a tea for stomach upset. So who are you going to believe?
