I don't know why I didn't think about the juvenile leaf form compared to what the more mature leaves will look like. It happens in many, many plants that a juvenile plant will look entirely different as it reaches maturity. When I enlarge your first photo, the leaf at the top left in the picture looks like it has a little "pucker" to the margins so you might very well have the cultivar 'Puckered Up' which grows 3 to 4 feet in height.
