"A weed is a plant that is growing in the wrong place." - Jim Crocket

I am on the fence about it. It does seed itself where it can, but I don't find it to be too bad. I let them grow here and there in the less formal areas of the yard. They have great medicinal uses, apparently.

I'm not even sure I'd know a motherwort if I saw one. The images on google are very variable. What does yours look like?

diggingthedirt - these are some pictures I took in late June/early July. Do these help?

The plant (at least mine) get about 3-4' tall. The stems are "square", the blossoms are right on the stems, at the leaf node. I had blossoms through early September. (And I do recall a thread on the "Name That Plant" Forum, where some one thought there neighbor was growing marijuana - thinking motherwort had marijuana shaped leaves.)
