The English orchid forums are a good source of culture info, R Rawdon Jester is named after the city of the hybridized and they are called 'Clown Orchids' so they added Jester. These can be larger plants, than my blooming R Aztec Fire, noted for the blooms up to 7-8 in ( they may mean cm). I've just discover the Clown Orchids and I'm trying to soak this up, they are saying repot only when the new growth is about 2 in high because that's when roots start, other wise you may lose the plant. But you know England never gets the sun that I do or the heat, so I think I'll group them with my strap-leaved paph and bring them indoors with 90's temps.
Here she is this morning, very windy here so may be blurry a bit, but you can see this is a 3in pot. My R Rawdon Jester was budded in a 4in pot.
