Dear Anonymous who left the comment on the picture of my grandmother's angel wing begonia and did not leave an address for follow-up,
I have seen some begonias similar to this at plant stores. Lowe's usually has at least one of this type (maybe not exactly like this one) every year. I would suspect they are only found in the southern plant stores.
This is a cane begonia and eats a lot of plant food, water and light. Most state plant laws prohibit individuals from sending plants via mail across state lines, otherwise, I could send you a clipping to root.
I did not take care of the plant much during this winter or summer and it has bloomed only once, but I expect it to be beautiful again next year.
Good luck.
