Give us tree!

Okay, what the heck kind of tree is this? In the fall, they're covered in rusty-orange flowers. Pic is under cut. If it helps, I live in Houston. (Zone 9b) Also, why saffron is so expensive. Please forgive the crappy phone camera pics! This is the tree. These are two saffron crocus flowers, and the saffron I was able to harvest from them. Three have come up so far. I think I'll need to wait a couple of years to get a decent harvest.
