slender false pennyroyal, Hedeoma acinoides

At first glance these little annuals look like a close relative of henbit. The flower shape and color are good for that. But we know that flower shape and color are the most changeable part of plants, and the most unreliable parts for identification. So instead we look at the calyxes, right behind the flowers. They are swollen on the undersides. Aha! It's a pennyroyal, even if it's not blue like the ones at home. These little plants give the impression of a weed, but they're Texas natives.
