"Insignis" = A cross between Brugmansia suaveolens x B. versicolor that hang almost straight down? It is supposed to produce large flaring blooms. This sounds like the species of brug that I prefer and quite possibly be what 2 of mine are. This species originated from the Upper Amazon of Colombia, Ecuador, Peru and Bolivia. They prefer warmer climates.
Has anyone grown Emily McKenzie? If so, does it produce a larger bloom? What about Dr. Seuss? Are both of those large bloom producers?
