Thanks for all your comments and tips everyone!
Black and Blue is always a true annual for me every year and I treat it as such. It dies with the freeze and winters we have.
This year is the first year that I planted it into a 24 inch container. Along with Black and Blue, I planted a couple of Pelargoniums (annual geraniums), a couple of Petunias and a few Salvias. Black and Blue has really taken over the pot and not left much room for the other ones. Salvia 'Mulberry Jam' is the only one that shows more blooms than the others at this time, but it is squeezed out on the side of the pot. It is also a taller Salvia in the pot, so that might be why it is able to hole its ground somewhat. To me and my experiences with Black and Blue, it needs to be in a container by itself, as I've done in previous years and not add other plants with it, since I want the others to grow, bloom and be their best. I've it just outside our patio door and the Hummers love the flowers. I think next year, I'll plant it by itself at the back of our side entry driveway in a spot that will get afternoon shade.
Whenever the unusually high heat and humidity moves out next week, I'll try to take some pics of it.
