Agave lophantha 'Quadricolor'

Agave lophantha 'Quadricolor', when this plant came out I hade several of these stolen and couldnt keep them in my collection for anything. Even had someone tell me they were solitary and tried talking me into a $60 dollar plant hat was smaller than my fist. Still one of the most striking agave variegates out there. These do not seem to be hardy below 0F. I have tried many times and always end up with goop. These are 4 year old plants in 5 inch pots. They are a very over grown but they want to come home with you.
