Thanks dbarron. I've told mom not to get her hopes up. They are coming up from the ground now so at least we will have some experimental plants to watch. I'm afraid that they will not be too happy with our hot summers. Perhaps it would have been better to plant them earlier in the spring. I'll try to report back what happens.

To be honest, when we took that picture we were hurrying as time had gotten away from us, so I didn't actually smell it. When we first parked and I saw it, I thought it was a giant Dogwood tree.

It was me! I am the guilty party. <hangs head in shame> I thought I had it (the species had "corn" in the name -- I can't remember what the full name was), but posted too soon. Upon further research, my answer was wrong, wrong, wrong. I deleted to try to hide my hasty and erred posting, but got caught. Someone PLEASE find the answer, it's driving me insane. I had these disturbing dreams last night, "Blue wildflowers in Texas, help me internet" .... and Google tortuously kept showing me nothing but Bluebonnets. WHAT ARE THEY. I need to know before I go to sleep tonight!

After an exhaustive search, I'd put it in the Pediomelum genus. Perhaps pediomelum cuspidatum or pediomelum latestipulatum. Here are the other options. http://bonap.net/NAPA/TaxonMaps/Genus/County/Pediomelum
