Possibly one of the widow's tears/spiderworts for the blue flowers? Straggler daisy (Calyptocarpus vialis) for the yellow ones.

Not sure about the tall one, but Horse Herb with the yellow flowers.

Isn't that the plant Ivy was clutching as she shuffled off the coil?

The one with the larger leaves looks like some False Day Flower, that has purplish flowers. Mine are just starting to bloom. The true Day Flower, or Widows Tears, has more bluish flowers and blooms a bit later.

I agree that the yellow flowering plant is horse herb. Not familiar with the larger leafed plant.

"I've seen it.planted in malice plant gardens."

I may be behind the times, but what is a 'malice plant garden'?

That's a very good question. I'm assuming this somehow relates to a book by Houstonite Ainy Rainwater titled The Malice Plant. "Gardening with intent to kill," one reviewer comments. Just what sort of gardening circles do you move in, Winterfell?

Maybe a Erect Dayflower ( Commelina erecta) , Virginian Dayflower (commelina virginica) or a Fase Dayflower (Tinantia anomala). I am leaning towards a the False Dayflower, But google them all. They are very similar

All similar enough to be known as Widow's Tears... gotta love common names. Assuming the photo is recent, agree on likelihood of it being t. anomala (false dayflower) based on what linda_tx8 said about it blooming already. Don't have it around here, but the commelinas we do have are nowhere that close to setting flowers even after accounting for the lag from being well north of SA.

Wantonamara's link mentioned t. anomala is an annual - is that right? If so, I had the wrong impression that all of these "spiderworty" natives in the Commelinaceae family were perennials.

Dayflower & horseherb. Both "weeds", technically, but both make good flowering ground covers in difficult places, like dry shade.

I came across a large patch of this plant today, off the rear patio of the Hanging Tree Saloon in Bracken. I have the impression it was set out many years ago, in an attempt to add some interest to an otherwise drab, shaded area. It was beside a large patch of purple heart. I suspect our mystery plant does belong in the spiderwort group.
