I don't have any place I can keep them indoors, but I experimented with one salvia in the basement this year, so I'll see if that wakes up once it gets warmer. I love your rows of flowers, that's a very pretty combination.
It took several years of growing salvias before I got to the point of having hummingbirds daily, so just keep growing what they want. I used to get them just during spring and fall migration at first, but now they stick around all summer. I also found that having several different types and colors of flowers worked best. Wendy's Wish is a big hit with my hummers, the Skyscraper series of salvia, and Purple & Bloom. And not a salvia, but Cuphea Vermillionaire is always one of their favorites along with the red flowers of Cardinal Climber.
The other thing that helped a lot was having the plants out very early to catch the early males migrating. For me that's by May 1st. I had bought some early one warmer-than-usual spring and just had them sitting on the patio still in their small pots and noticed the male hummingbirds were coming to them. Since I've been doing that is when they started sticking around and I now have them daily.
