Dear Clarence,

  The inflorescence of Xanthosoma violaceum quite pretty. The spathe tube 
is purple outside and white with a pinkish base inside. The spathe lamina 
is greenish-yellow outside and white inside. The spadix is also coloured: 
The fertile male flowers are cream, the staminoidal zone is pink and the 
female zone is strongly yellow! You have to see to believe it! And about 
the smell... well it smells like a Xanthosoma inflorescence!!! (At least 
it don't smell like baked yams)
  This Xanthosoma seems to survive aquatically. I had one in my fish tank 
when I was a little boy. The plant could produce new leaves but smaller than 
it usually does. 

I hope it helps,
