Central Florida (Zone 9a) I recycle, reuse, repurpose!
Wonderful! I'm a lover of the Hardy Begonias as well. I had them in Knoxville and they were in a planting bed at the corner, with shade until evening and then the setting sun. I have seen them E n masse at some gardens and they are magnificent!
My friend E down the road has masses of them, but nothing I do seems to work. She's given me plants and seeds and still nothing. Her brother insists I try again with plants, so wish me luck!
