Someone on another forum said they had a larger screen sized television and you could tell that the flowers were fake. It makes sense because I was wondering how all those flowers were exactly the same size and shape. I think the orange looked too orange as well.

I have grown brugs in a pot together as well as three braided brugs together in a pot. It is hard to get them all to bloom at the same time and one will always try to get larger than the other two etc. The pot they had all those in was too small in my opinion to get that kind of blooming and bushiness on 3 brugmansia together.
Maybe if you put them in a half whiskey barrel and root pruned and fed them alot of bloom booster etc. you would have better luck.

I guess you could take three individual blooming plants out of thier pots and combine them and then take the film/photos lol.
