Have you ever grown anything from seeds before? It's really amazing to think that a huge plant could come from a little speck you put in some dirt and added water to! A few years ago, I got a bunch of different flower seeds for my first time and I planted them in little pots on our back deck to see if they would grow. This flower looks like one of the types I planted, so I think some seeds must have blown off the deck and found their way to this little area down by our well house.

From Wiki:
Phacelia linearis, with the common name Threadleaf phacelia, is a species of phacelia. It is native to western North America from western Canada to Wyoming to northern California, where it grows in forest, woodland, open scrub, and other habitat.

A HUGE THANK YOU AND HUG to my ipernity Pod Sister, Pam J, who solved the mystery of this flower, which I couldn't identify!
