I bought these with the label stating deck planter (nothing about it even being Musa sp.). The very stout p-stems are 7 to 9 inches and the plant from soil line to the tallest leaf is 18 inches. The pot is small which I believe is dwarfing the size. I think these are Super Dwarf Cavendish, am I correct? Or maybe Little Prince. My Truly Tiny does not have any wine marks, or pink, red, or black on it anywhere, so I don't believe they are TT (though I have seen pictures that do).
Beautiful Wine marks on the leaves

Ruffled red petioles

Some pink and black on p-stem

And beautiful pups
