Last year this mystery plant started growing in the stone strip on the south side of the house. I thought somehow a wandering jew house plant had seeded itself, but I haven't had one of those in decades. This year it has flourished and has clearly become invasive.

So I just googled "weed that looks like wandering jew with blue flowers" - and here I am! Now my plant has a name!

It's joining the myrtle, honeysuckle, and (yes) occasional poison ivy vines that are going crazy down there.

So, what do I do? Let it grow, or get out the Roundup??
