What's this weed?

Every year, I seem to get a new weed in my gardens. Anybody know what this one is?

I wouldn't really call it a weed, it's Selfheal (Prunella vulgaris), a native (probably) wildflower.

Yep, also called 'healall'. One of my favorite wildflowers!

Thanks! Great to know it's not a weed :-)
