It will grow all by itself, and it is a great addition to green smoothies, of which I prepare one each morning. So, when you have an abundance of Commelina cyanea in your yard, just eat it!
By the way, it is wrong to call it "Wandering Jew" or "Chreeping Christian" - bot. Tradescantia fluminensis). That is a totally different plant, with white flowers, not blue, and NO single row of hairs down the stem!
So, eat the blue flowering Scurvy weed, it is very rich in vitamin C!

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??
