If there is anything noted after the name, it will usually look like FCC/AOS, AM/AOS, HCC/AOS, etc. These are indicators that this particular plant was given an award. FCC is a First Class Certificate awarded by the American Orchid Society. AM is Award of Merit and HCC is Highly Commended Certificate. See the list of awards given by the American Orchid Society here.
Another reason for adding Rlc. George King ‘Serendipity’ AM/AOS to any “must have” orchid list would be its easy growing nature. It is adaptable to a wide range of cultural conditions and seems to produce flowers in most. Bright filtered light produces the strongest plants but this hybrid can be grown shadier and may be suitable for windowsill culture…if you have a big windowsill. If you grow any cattleyas, you can grow this one. Ideal conditions would be those outlined in our culture sheet for Cattleya. In our climate (Florida) we like to grow cattleyas in somewhat coarse media because we have an open shadehouse and constant summer rains will rot roots as the media deteriorates.
