Phalaenopsis speciosa C1 a.k.a. Phal. tetraspis C1 or Phal. speciosa var. Christiana
Coolest phalaenopsis species because of unpredictable randomness of red color. I bought it with label stating Phal. speciosa C1 few years ago. It blooms often with many flowers at once, but doesn’t grow into large plant. Old leaf sheds away when new one comes out. Not sure why.
