I grew Blue Fortune only one time. It did not like my Mississippi humidity. Once the first flush of blooms that came from the nursery died, it bloomed little or none the rest of the summer, and did not return at all the next year. I have far better luck with blue salvias and angelonias.

I tried that one years ago and it fizzled...next spring look for "Busy Bee Blue". Mine got huge and was covered with flowers and bees all summer then suddenly went dead, but lots of babies are carrying on in her place...I think it is much better. BTW, deadhead!
