Maybe its the pic, but they don't look too different to me. I often find 2 otherwise identical plants and growing conditions perform quite differently due to who knows what. Will those be okay outdoors in 6A?

I would not worry much as their root systems were not necessarily the same although the top of the shrub was. My potted Pistachio has just two blooms plus a tiny one that can probably be measured in 1... 2" tops!

jweingarden and luis..thanks both of you for the vote of confidence..I guess since I've seen them everyday I could see one was better..jweingarden - they won't stay out when cold weather hits..I have 7 in pots that I overwinter in my shed..my only hope for blooms..luis - Pistachio IS compact but yours is really a baby!! I hope both of ours grow a lot next year..
