ya, definitely not thai dragon.
one grows certain peppers to fulfill a need. i have no reason to grow cayenne because the flakes i get for a dollar/pound are fine.
but i do grow the cayenne variants like goatsweed as my house pepper and it makes a killer powder, plus frozen pods dropped into stews or soups really elevate a soup.
growing kung pao, a cayenne type, is beneficial in the fact that it has a mild cayenne flavour but adds just the right amount of heat and flavour to a stir-fry.
jwala or indian finger pepper, which might be what you have(but my guess would be a large, narrow cayenne), is still another cayenne type but not as hot but still gives that cayenne flavour. it is fun to grow as the jwala can grow quite large and is fun in a competition as who can grow the largest.
pepperjoes sells a charleston pepper that is suppose to be the killer hot of all cayennes but i will stick to my goatsweed for heat and flavour for soups/stews.
maybe one day Dad and Marine son can have a hobby, who can grow the largest jwala or hottest charleston..... best wishes.
