They are usually available here with the green leaves or the burgundy tinted leaves. The "arrow" or "wing" shaped leaves are the hallmark of the dragonwing begonias.

Looks like 'Withlacoochee', or 'Chocolate' to me. Check out thelmae as well.

I think Butch is on the right track. 'Withlacoochee' has a wider leaf, and more of a bronzy look I think, and B. thelmae maybe has smaller leaves. I've lost them both and I'm runnin' on memory, which doesn't always serve me well. Don't know 'Chocolate'. There's something tickling in the back of my mind, but I can't bring it out. It'll come to me--maybe in six months or so!

Hi, Thank you for help so far.
I have checked the 'Withlacoochee' and 'thelmae' via Google Imagesearch, they look very much like the
Begonia i have, i couldn't find a proper image tought,
only racher small about 200x200 pixel images. But what i can tell from the pictures i did found is that 'Withlacoochee' has more green leaves than my begonia, Leaf coloring is more B.thelmae's.

You might try checking out the Houston ABS site...they have lots of good pics & info.

I've had Withlacoochee, and leaf color for me has depended upon light conditions, also.
