it has to be Black and Blue Salvia.
It will grow in shade and every where else, too. In the DFW area it is a little invasive. No real winter to keep it in check here. I would wonder if it would be worse for you. But if you have a large wild area it would be okay. If you would want a tamer large blue salvia I would go with an indigo spires and it grows and blooms in the shade! Not a full Texas sun plant.
May joy and happiness be yours this week!
