I love those dangling roots, Ross! This baby is so sweet.
I have Gastrochilus japonicus, but I've yet to flower it. It has what looks to be three spike 'nubbins' that have just been sitting there waiting for the past 3 or 4 months. Still green, but not growing. Plenty of root growth, though, and a new leaf - so maybe once the leaf has matured the spikes will start to grow out?
