Tiny 3-petal blue flowers, Commelina?

Tiffany, purpleinopp GardenWeb, Z8b Opp, ALOctober 2, 2012

Found locally in a "wild lawn" area adjacent to a pond, part sun. Roots and shoots at each node, leaves about an inch long, plain medium green, flowers were in a sheath like Commelina communis, but with a 3rd petal, and much smaller than C. communis I've seen before. Inside the sheath are tiny yellow things on white filaments - stamens?

Didn't have my camera out there, just phone. Brought a piece home, completely wilted and the flowers have closed, but it's available to consult since my description is not very scientific.

A different Commelina? A Tradescantia?

It may be the native dayflower - take a look at a couple of the pictures in the Image Gallery in the enclosed link.

Here is a link that might be useful: commelina erecta

If that bottom petal turns up like a small cup, flowers are tiny and all three petals are blue, it is probably Commelina diffusa.

A scourge. It's taken over my beds and I can't get rid of it.

Thanks for the replies!

I hadn't realized there were native Commelinas. I'm pretty sure this is the diffusa, from the way the 3rd petal is so visible.

This was a really pretty patch in the "lawn" but agree, eahamel, probably not something I want to unleash in a flower bed.
