Trying to ID invasive plant: mint or fireweed?
Hi folks -- I've got a plant that's absolutely everywhere in my yard right now (in Eugene, OR) and I'm trying to figure out what it is. It has no odor, so although it looks mint-ish I'm thinking it's something else? Someone suggested fireweed, and the leaves do look similar but photos of the shoots don't match what I'm seeing. Any ideas?
Here's another look at it: http://i.imgur.com/4D6Nasa.jpg
