B. ‘Insignis Coral’, B. ‘Insignis Gold’, B. ‘Insignis Orange’, B. ‘Insignis Pink’, B. ‘Insignis White’, B. ‘Insignis Yellow’, B. ‘Insignis Yellow/Gold’: despite their names, none of these American plants is a cultivar of Brugmansia insignis. Nevertheless they do not transgress any rule of the 2009 ICNCP because the epithets are not entirely Latin nor entirely composed of a botanical species epithet, so they are potentially able to be established. As far as we know, only B. ‘Insignis Orange’ is established and, since the 2009 ICNCP recommends against the establishment of names where the epithet gives a false impression of, inter alia, the cultivar’s origins (Rec. 21J), we do not intend the rest be established. An alternative interpretation is that the names were originally intended as Brugmansia insignis ‘Coral’ etc. in which case they could potentially be established as B. ‘Coral’ and so on. In some cases those names are already occupied for different plants, but were they not, the 2009 ICNCP also recommends against the establishment of cultivar names with purely descriptive epithets (Rec. 21G). Why so many cultivars have been erroneously attributed to this species is not clear, though we note that B. ‘Insignis Pink’ (despite being applied to various clones) resembles B. ‘Frosty Pink’ which has been cited (incorrectly) as a first generation hybrid between B. suaveolens and B. versicolor ‒ the same species cited as making up B. insignis at a time when that species was itself thought, again erroneously, to be of hybrid origin. The others may represent the extension of these errors. B. ‘Insignis Pink’ has the established alternative B. ‘USA Rosa’. Although it is an established name, the application of B. ‘Insignis Orange’ is confused, and some material distributed under this name has been named anew as B. ‘USA Orange’ (q.v.). B. ‘Insignis Gold’ is another name of very confused application, having been applied over recent years to entirely different plants in the USA, one resembling B. ‘Ocre’ and another B. ‘Charles Grimaldi’.
