Lovely, Jim. Is your white begonia fragrant? If it's the same one I have (and it looks just like it) it has a wonderful perfume in the morning just as the air is warming up. Go have a sniff about 10 or 11 tomorrow morning.
Beautiful amaryllis, I've been circling around some of those stripey ones for a while, and I think I need to get some. Mine are just putting up buds, but they are on the north side of the house, so have stayed very cool until just recently.
Thunbergia has a couple of blooms open, and Braz. Red Cloak came through the cold weather without even a blankie.
My huge row of Shooting Star clerodendron were just opening their flowers before the cold weekend, but don't seem to have any damage, surprisingly.
