Can anybody help?

There are so many, thousands. When you get some flowers, that could help. I gave up trying to name my Begonias. Knowing that this is a cane type (a very pretty one!) should help you care for it. From there it's just a matter of finding the sweet spot of light that makes it bloom. Is it living inside or outside?

While it could be several, it resembles, very closely, 'Snowcapped'. If you Google Begonia 'Snowcapped' you will see the resemblance.

This begonia is growing in the house (inside). We can place them outside only in the warmer months.

I know that there are many hybrid begonias. But I was hoping someone could help me accurately to call a hybrid. Unfortunately, in the Internet, a lot of photos of begonias are signed not correctly.

Has Begonia 'Snowcapped' thin, delicate leaves ? Leaves of this begonia are thinner than, for example, leaves of Begonia 'Corallina de Lucerna'.
