This particular one is very much like a Cane Begonia which creates a lot of branching almost like a shrub type however it seemed to be like a sensitive slow growing type which makes it challenging to grow like a hardy condition.
Often I had notice that there are some with similar names like "Begonia Sinbad - Pnk" and Begonia Benigo but I had not found any difference or if there is - it might be a some slight variation on them.
One of the interesting plant feature is the dot-dot features: Tiny uniform dot formation on the foliage surface creating nice evenly patches that creates a strong white and pink visual on a light green background. Very similar like a maculata species leaf design - that is if you are a dot-dot collector.
Another similarity is Begonia Burning Bush - both have the same structure with different coloration.
This is the appearance how this begonia looks like when it had grown bigger into it's fully maturity.
