What is this type of (Greek?) chilli pepper? The chillies pictured below are fairly common in Greece (particularly the north of the country). They are known as "kafteres" (καυτερές) which roughly translates as "spicy". 



I'd like to have a steady supply of them, however I don't know what they are called outside of Greece. What is the name of this variety, and would it be feasible to grow them in the UK?
It's a Frigitello pepper, although in the states they're called pepperoncini. You can grow any spicy chili pepper in the UK provided you have a greenhouse or maybe a conservatory, otherwise don't bother, it just isn't hot enough. 

You can find these types of peppers in any turkish and many asian supermarkets, so no need to grow them.
