Phalaenopsis Dimension is another trade name - I cannot find this as a registered orchid on RHS website. This flower looks familiar, but I cannot think of a name right now. It has finer spots than Dtps Leopard Prince. It would be great to know the parent flowers of this beautiful hybrid.
The real hybrid name could be Phalaenopsis Rousserole (Phal. Cataracte x Phal Frisson), by Maurice Lecoufle.
Interesting debate here: Phalaenopsis Dimension - Forum Orchidspirit .
I think they need very shady spot or they get sun burned?
As with most Phalaenopsis hybrids, direct sunlight around noon is to be avoided. However, a couple of hours of direct sunlight after sunrise and before sunset would be good.
I'm afraid that 'very shady' might be not enough light.
