This is what Texas bluebonnets look like in winter. We have lots of them. They're beautiful come spring, but the blooms only last a couple of weeks.
While I was out taking photos of the bluebonnets, I came across several of these strange plants. I'm thinking that it may be some kind of mushroom/fungus thingy. Weird. The seed/flower structure eventually pops off, leaving no discernible plant in the ground. I dunno, though, maybe this is the entire plant. (The black stuff is sealcoat overspray from the driveway.)
