Natalie, EE would just simply mean that it will bloom a week or more before your peak bloom which would be the mids. You are so right, temps do change a lot of blooming pattern from warm to cold climate. I have a few of Pat Stamile's EE that I got last year. John Hawkins, sev, Clear Mountain Morning, EV, and Quartz Rainbow, EV. He had good things to say about them that convinced me to try them here. We will see.
