Are these chillie peppers?

[SvilleKid]

NOT Jalapenos. Leave and plant structure is wrong for those. The only peppers I've ever planted that grew upright like these were Tabasco peppers. However, the peppers turning purple rules those out. The images I've seen for Tepin peppers show them as small, round shaped peppers like birdseye peppers. The best guess I can say, is the leaves and plant structure look mor like serrano peppers than any I can think of, but never seen them turn purple, and they generally grow down. Any possibility they are a stain of Thai peppers? size and upright growth would support that possibility. Chili peppers can go thru wide range of colors, including purple, so it is probably a form of chili. given the small size, I'd say expect them to be very hot!
