I think you need to post a photo of it when the new leaves come out. The old leaves on this plant are past their prime.

There are dozens or hundreds of begonias that look very similar so you need to look at leaf size, color, shape (cleft leaf), spirals, and flower color as well.

Try the Astro branch begonia web site. It is a good place to start at.

The international database of begonias may have more photos to search but is a bit more complicated to find (no thumbnails to search). Go to Find, Advanced Search and enter Plant Type (rhizomatous).

Ask Lue. She'll know. :)

She planted a begonia that looks similar in my backyard and it's loving it there.

lol. I will. I inherited a whole bunch of plants (not the begonia) from our friends who are moving to CA and of course cannot take their plants. Looking for spaces for all these babies.

Again, she'll help you. I was gifted some rain lilies and when Lue comes tomorrow, I'm hoping she finds the perfect spot.
