Elaine - I have mine growing in 18 gallon plastic bins. The bins are light-weight. I don't have any named brugs. (Or at least I don't know what the names are.) I also purchased some seeds from ebay late last summer and managed to get some of the seeds from each cross to germinate. Each plant looks different. I am waiting on blooms to appear (hopefully soon). I love being able to move them around my yard, too! I was hoping they could survive in the ground, but I had a feeling they wouldn't. Had to try it anyway ...
Here is my espalier Brugmansia:
This is another cutting of the same plant growing without being pruned. It certainly has more blooms, but unfortunately, it is hitting the fence. But I prefer more blooms like on this one:
