I've looked a little more, and one thing that has me stumped about Castilleja cusickii is that it says it grows in moist areas. The area where this plant is growing is anything but moist. Yes, we do get rain here, but the area it is in is so rocky that there is very little moisture, as well as very little dirt. A couple of sites stated that it normally grows at mid to high elevation, but I'm only at 1,650 feet. To me, that is rather low. Maybe it's just a fluke that it ended up on my property. Hopefully it survives and reseeds. I really do like it!
