Flower Friday - Begonia

This is a plant that lives in a large pot outside the conservatory door.
It is a type of begonia,  I understand from consulting Plant Snap.

Either Wax Begonia, curcullata begonia.  Or Begonia Grandis Dryand, Hardy Begonia.  I love to see the mass of them together, but each single bloom is very attractive. I have added a close up as an extra.

Thank you Biker Bear for continuing to host the lovely Flower Friday challenge.
