My first Vanda were given to me. There was no internet available at that time to refer to and find out what I was doing wrong, so they died over a winter season. This was a long time ago when I was in grad school at Vanderbilt University in Nashville, Tennessee.
Recently (June 2013) I was looking around this forum and came across the subforum: Vanda Alliance -- Neofinetia. Based on suggestions from members, I bought four, Neofinetia falcata plants. These four are not only surviving but I now own many more of them in just five months. These orchids are really easy to grow. Because of their miniature size, I can grow four to six varieties in the same space as one regular Vanda.
Here is a picture of one Neofinetia. Doesn't it look like a Vanda? This picture was taken a couple of weeks ago. The flower spikes have grown taller.
