Carolyn, I'm surprised to hear that about Peach Flambe. Love Georgia Peach, very hardy and great color. Peach Melba is reliable, but a slow grower for me.
Pistache is my favorite so far of the limes. Vey Hardy and great color It can get a spotted brown fungus if it gets too wet, but a quick spray will clear that up
