They are all tuberous begonias.
Reply:The first two look like Begonias to me, based on the shape of the flower and what I can see of the leaves. You might try to Google that for clearer information.





I can't identify the third one from the picture, is it a hanging plant, vine?
Reply:Don't know about 2 %26amp; 3, but 1 looks like a double begonia.
