This Ada (Brassia) aurantiaca just keeps getting more prolific every year. This year, I count 13 spikes so far, but there could be more - they sneak out from the leaves, and I don't see them, they're pretty well camouflaged until the orange color develops as they get ready to open. Flowers are quite long lasting, I expect it to dazzle for at least a month. Grows on my patio.
