Begonias are easy to grow here. At the end of the summer I plant them in the ground and they usually come back the next spring. I didn't have any luck with that this year so I had to replace all of them. I like the green leaf pink ones. I think the name is Olympia Pink.
Sometimes I put them in a pot all by themselves and sometimes I mix in lblue obelia, white or pink bacoba, petunias, pink or purple verbena, and a little variegated vinca vine for added green.
