Scientific name: Artemisia vulgaris
It smells like sage, but I am also highly allergic to it. I love the smell, but will usually start to sneeze right after brushing against it. Pulling it will send my sinuses into an unpleasant day-long battle. You can probably tell what it is by the smell – you can also flip over a leaf, and the underside will be very light-colored.
I hear it has some uses, but it’s non-native, and highly invasive. I don’t want my entire yard to be covered in it, so I must pull it.
