Hi all!
I've found this lovely little "ufo" in my backyard in a few shady spots. Its square stem and the shape of the flowers and seeds make me think it might be some kind of salvia, but I really don't know! It smells really good - very sweet, almost like a less-powerful honeysuckle. Also, I don't think it shows in the photo, but some of the leaves on each plant have purple around the edges and along the veins. Unless it's invasive or hard to control, I think I'll encourage these little guys to spread around - so pretty and they smell delicious! :)
