One of my favs. Mine faithfully produced 2 spikes of flowers every May. Unfortunately I had a semi-calamity with my shade house over this past summer and my retusa was lost. The good news is I have pre-ordered a new one from Ten Shin that I will be picking up from them in 2 weeks at our local orchid show.
I have three. Two are mounted on trees. The one in mango trees produces a spike now. But too high to take picture. The other one have nothing this year. And this one is the biggest of all three
