Looks like Black Salsify (Tragopogon porrifolius), non-native.

Here is a link that might be useful: salsify

Pops up in my front yard. Kinda pretty. Hard to dig out though. Tenacious roots. I always wondered what it was. Now I know.

This weedy thing can really self-sow with abandon if you have it in or near your yard, and can take over if you let it go to seed. It is able to grow with virtually no summer water, and will germinate even in the middle of summer. My advice would be to eliminate it before it takes over, if you have it in your garden. The long tap root is very deep, and will resprout if not completely removed.

I agree. Looks like the "oyster plant." The roots are edible and taste kind of like oysters. Very deep and long tap root.
