Looks a lot like cedar sage (salvia roemeriana).

Yes, it looks like Cedar Sage to me also! I love the fragrance of the foliage. I just had them in my flower beds until one year, just on an impulse, I scattered seed on an area to one side of the driveway, which is a bit shaded most of the day. They grew and naturalized, surviving through droughts without any watering, blooming every year.

I love them, Mine were wild on my land. They will seed themselves and slowly get a ground cover going. They bloom at the same time as ajuga repins and columbine usually if you like color combinations of bright primary colors.

Like linda says, tough as nails if you have well draining soil. They grow in cedar breaks in the hill country. They will not turn up their nose to a Escarpment Live Oak.
