Dave,
The second one you are calling "Blue Toro" is actually Xanthosoma violaceum, a very attractive plant. I have one just like it in a very large pot. I'm waiting for it to bloom - I've seen the blooms and they are very nice, but it is the pollen I'm after. I've got a top secret hybridization project I'm going to move forward on when the right plants are blooming.
