Not that it makes much difference but it's a cultivar called 'Little Princess'

On the Little Princess part... I just bought a JM that was listed as Kiyohime "Little Princess", do you know if yours is a variety of Kiyohime or a separate cultivar? I can't find any listings that explain exactly what it is....lol
