Lovely Green Dieffenbachia

I have different kinds of these plants in my garden before.  Since I don't live anymore in a tropical country, I can no longer grow Dieffenbachia outside. These are houseplants but since most of our windows inside the house are already filled with plants, I can't either have it.

Dieffenbachia is a genus of tropical plants in the Family Araceae noted for their patterned leaves. was named by Heinrich Wilhelm Schott, the director of the Botanical gardens in Vienna, to honor his head gardener Joseph Dieffenbach (1796–1863).
