Molly, it might be a good idea to pot up your Angel Trumpet cuttings in case it's another month or so before it will be warm enough to plant them outside. The roots get wimpy if they grow too long in just water.
Don't know about where you are, but here, they do a lot better for me if I keep them in large pots. We have nematodes in the soil that just love Brugs. If you put them in ground they will do fine for a while then start petering out slowly, if you have nematodes.
