This one too...where it gets a bit more sun it gets this deeper color, in the shade it's not as noticable
Other one to id
Some form (hybrid) of heracleifolia. You could check with the international database of begonias for all begonias with a parent of heracleifolia. It must be popular or underpowered since it says the maximum number of sesssions has been reached.
got the same message you did...so I'll go do a little diggin now that I have a bit more to go on.
Thank You !!!!!!
