Cattleya dorminiana var semi-alba

[NeofinetiaCanada2014]

This plant I purchased at the 2005 Japan Grand Prix show in Tokyo, ten years ago. Unfortunately it bloomed normal colors, brown sepals and petals with purple lip (with two flowers!) A semi-alba would have green sepals and petals with a purple lip. The reason was that it was a selfing of a semi-alba, proving that semi-albas are a recessive gene. If I selfed this, the chances of getting semi-albas would run around 50%. Where's my toothpick?

I grew this plant hydroponically in a square plastic container, perlite on bottom inch and a thin layer of NZ moss on top. Surprisingly it has done well and kept all leaves since a seedling! I let it dry a bit between waterings, watering very lightly. I spray it humid almost daily. I fertilize it every two weeks with little amount. Seems to work for 10 years! I keep it warm and bright (shaded south).
