I must admit, I have eaten some of my blooms. I have been served orchids on platters before at restaurants, and tried them knowing that anything they put on the plate is edible. I have also eaten some of my phal blossoms, but only after they fall off. I must say, they are rather tasteless.
I have also used them as decorations on plates, but usually only when I serve a plate of something to my wife, since I usually only lose one bloom at a time. I guess I need many more orchids to be able to decorate our plates daily!
