Prices are finally coming down and I was able to get this gallon size ES for $20. instead of $40. which seems to be the going price around here.
I'm real excited because I can't even grow Annabelle which is suppose to be hardy in Z5 but its branches die back for me every year so no blossoms.
Anybody growing ES in Z5?

BTW its blooming blue now because I just got it by my Nikko Blue that sometimes maanges a couple of blossoms blooms pink so what does that say about my soil and what do I have to add to it to make it bloom blue?
