Ann,
I put in a lot last spring. I created a new shady garden/reading nook. It is under a group of tall trees. The garden gets morning sun, dappled shade all day and late for about an hour at day's end. The bee balm did well last year and it is coming back with lots of new plants starting. I'm going to have to thin them some so they have better air circulation.
It doesn't get as lush for me here as it did in my Ohio gardens. The humidity takes a toll on it. But, I'll try to keep it going as the hummingbirds love it.
