aswan,
You are right about it being a total crock. Brugmansias are not like hydrangeas whose flowers turn blue under acidic soil conditions and pink under alkaline soil conditions. They are more influenced by weather, heat, cold. Most Brugmansia blooms will not develop their "true" color until they have been open a day or two. As the bloom pushes out of the calx it emerges with a greenish tinge, then turns white or a yellowish color as the lobes start to spread. Most Brugs are hybrids and depending on the species mix will start off white or yellow. Then develop color so It's possible to have more than one color exhibited on the plant. Many Brugs will bloom a paler color in winter than they do the rest of the year and may be lighter or darker if grown in different parts of the country. Many pinks will not get as dark when grown in California when compared to those grown in, say, Florida. Others never develop their "true" color. One of my favorite doubles is Creamsickle. Its color is listed as Apricot in the Register of Brugmansia Cultivars, but mine has shown that color only once in 3 years and then only as the flowers were taking their last gasp. This is how some DGer's Creamsickle bloomed

A photo of mine is below.
A good example of what I mentioned earlier. This is a photo of Mountain Magic from the PlantFiles:

The shade of pink can differ slightly with every flush you get.

My Mountain Magic has bloomed twice while in the greenhouse this winter, but the blooms were a pale pink.
