Q. Why are there no blue orchids at the orchid show?
Blue orchids...well, you mean the blue Phalaenopsis (moth orchid)--that is an artificially colored plant sold in big-box stores. There is some work being done by crossing certain plants, so who knows what colors they will come up with in the future. High-quality flowers are available in the entire color spectrum (except true blue in orchids). The closest to a blue orchid color would be the Vanda orchids but they are really more of a beautiful purple hue.
For more information see The Science of Blue Flowers.
Hope this helps.
