These are the common types easily available in many nurseries and often freely showcased as indoor plants in many places. Often too, I find these pruned and thrown off and new offshoots sprouts out from the cane but also because it is exposed to elements - snails and slugs does most of the damage on the new unfurling leaves with lots of eaten or torn in between.
This particular type only have 2 tone colors - a splash in the center with a dark green border at the leaf edges. The cream colors appears bigger when it is exposed more to sunlight.
Another challenge is the names (ID) seemed to be interchanging with other different types and that adds confusion. I therefore have to make my own judgement on the best possible ID checking through the authenticity of the information.
