New (to me) flower

I'm not normally stopped in my tracks by a flower I've never seen before, but it just happened yesterday. I may not be able to identify every wildflower around here, you understand, but at least I can recognize almost everything (if that makes sense).

But yesterday morning while walking Mr. Darcy back home, I took our lower driveway and saw a flowering plant growing straight out of a gravel pile. Somehow I hadn't noticed it earlier, and I had never seen this plant before. The flowers were a fiddleneck style, similar to the lacy phacelia we used to plant in our old garden as a rich nectar source for our honeybees.

But these flowers were white, not purple like lacy phacelia. What could it be? I scoured my flower books and couldn't identify it.

Finally Older Daughter looked it up on a flower-identifying gizmo on her phone, and correctly identified it: Shade phacelia (Phacelia nemoralis), a native perennial. Well, what do you know. No wonder it resembled lacy phacelia. I've literally never seen these growing in the wild, much less thriving straight out of a gravel pile.

Online sources say it "prefers moist slopes, stream banks, and mixed evergreen or coniferous forests." A gravel pile is the last place I expected such a plant, but there's no question it's large and beautiful.

I sincerely hope this flower spreads (I may harvest the seeds and help it along).    

Not only is it native, but it's also a nitrogen fixer and an enormous attractant to pollinators because of its rich nectar. Woot!
