This is "Fuego F1".
This is "Hot Portugal"
This one is known to me as "Short Fat", but it's looking as if it might be "Cherry Bomb".
This is "Long Medium" - looking more like a Sweet or Bell Pepper every day!
This one is "Serrano". Usually the most prolific of the ones I grow, it produces masses of small blocky fruits. There aren't many just yet, but I expect there will be eventually.
The final one of the set is "Pinocchio's Nose". It hasn't set any fruit yet, but I think the first ones are about to form. It has fewer flowers than all the other, but that's probably because the fruits are individually bigger. Apparently they can grow to about 25 or 30cm in length, thought they always remain slim.
