Yes, my Crepe myrtles are blooming as are others in my area. Sorry, I am not specifically familiar with Muskogee, but I would suppose that your plant is still establishing itself and just not ready for blooming this year. It will probably bloom next year. My variety is Zuni (lavender flowers) and was a bit late itself I believe because I moved them in May. I wouldn't worry despite the lack of blooms for the season. Good luck!

I planted five crepe myrtles last fall. They were in bloom when I purchased them and luckily they survived the winter, but they have no blooms, while all the crepe myrtles in my neighborhood are already in full bloom.
I hope they will bloom next year.
