I have a young Arjuna wink vanda that should be fragrant when it blooms. These vary a lot, so I hope I got a pretty one. At $10 I couldn't help myself!
Beautiful blooms....your instinc is right: this is a Vandacious orchid....I also have this and its a prima donna....it is hard to grow new leaves and roots=it rarely blooms for me too....the others=like the giganteas bloom regularly for me.
