Hate the intensely blue moth orchids, the spray-dyed flowers in flower arrangements (we see a lot of them in the hospital). I saw the spray-dyed succulents a few days ago and hated them even more.
They wouldn't keep doing it if they didn't sell, but why take beautiful flowers and plants and spray them to make them look fake?
For me it goes back to tropical fish. I don't mind the Glo-fish type fish, where the fluorescent pigment producing genes are spliced into the genetic makeup of the fish, and as such is inherited generation to generation. OK, that's a bit bizarre and created a lot of controversy. But I draw the line at dyed fish. I was in the tropical fish industry for a number of years, and had my own store for a while. I did sell the Glo-fish, but refused to carry the dyed fish even though they were quite popular.
