This particular plant I did leave outside ( I am in Northern California), and was surprised that it survived. It is native to the Andes, so is perhaps the most cold tolerant pepper plant, and actually struggles more with our summer heat, than our usual winter temps.
I have overwintered many capsicum chinense in my unheated garage.
Espellet is apparently capsicum annum, and I think they might not do as well.
This is the manzano pepper link I was looking for. It is a capiscum pubescens.
