Your preliminary identification of Dieffenbachia may be correct, although I can
only reserve my final judgment until I see a photo of your plant.  My inclination
from your apt description is that the plant is an Aglaonema, perhaps the cultivar
'Queen of Siam'.  This once very rare hybrid Aglaonema from Thailand is now
available widely in the US market at reasonable prices.  The specimen I acquired
at the local farmers market this past summer was identical to a plant that went
for auction at the 1995 IAS Show and Sale for nearly $US 100.  This cultivar
grows very well and very fast for an Aglaonema, perhaps due to the hybrid vigor.
If this is your plant, you will be very happy with your purchase for a long time.

Take a photo and send it to Lester Kallus for identification online via the Aroid
Identification Center linked from the IAS home page or at
