The picture I uploaded was taken during the summer, and the plant looks green. But usually this plant is a bluish gray, but not white like a dusty miller. It grows quickly and weed-like, and last through the winter.

The plant smells if you move a leaf between your finger. Can't find the words but more like lavender or sage; definitely not mint.

Thank you for any advice! Since winter is coming I thought I might eat some if it is edible. I have a zoomed out photo if it helps.
