If anyone would be willing to take a stab at guessing what a few of these plants are, your help would be most appreciated! They are all about 3-4 inches high and growing around the lawn of my house - I'd like to figure out if they are something that the previous owners planted or just a weed.. I'm sorry in advance if the photos aren't great. Thanks! Edit: I guess that the second photo is Deadnettle - I presume that it is very invasive?
