Hi KD, I do not grow brugmansia here, but I do remember seeing them in the Philippines, usually in the cooler elevations in the area of Tagaytay. There is often cool mountain mist there which plants like. Temperature in Phil lowlands at times goes from 74F to 90F, while in Tagaytay it goes 70F to 78F. I saw some online photos of some other growers in the Baguio area, much higher elevation and temps there can go from 58F to 73F, with the coldest in January at 50F sometimes. The one I see is colored white.
I saw a neighbor of mine here growing their yellow brugs in a big container, but it is always protected by their porch overhang.
Maybe you can try it too, just protect it if it gets too rainy there.
I do tend to make a long thread of plants I grow
Conditions are so different year to year and reviewing them makes me understand later what truly worked and my errors!
