Phal bellina is in bloom and it's a tetraploid (so?)

[MJG]

This my a Phal bellina 4N that just bloomed. I've been reading and trying to understand what the physical differences are between a diploid and a tetraploid bellina. I understand the chromosome stuff. As I've been searching for other characteristics, I've come up with the comments that 4N bellinas have bigger leaves and are slower growing. Hmph. Can y'all offer additional insight?

Regardless, for me this is a magnificant plant. The leaf that you see in the forefront is 9" long and it's beautiful.
