I tried Lime Rickey a few years ago , but it did not overwinter. For me Citronelle has been by far the best of the lime colored .Key Lime Pie is nice in color but stays very small. My Electric Lime does not look bad so far , it was a plug last fall so not very big yet. I never tried Pistache, does anyone have a picture? I just got Pear Crisp last week, I hope it does well I really like the color and leaf shape of this one.
