Astonishing! I love the 'chorus line' of Brassias, they look like the Orchid Rockettes. Are those Arundina plants really like 8ft tall?
I guess being on the Equator, the climate is very steady and they never stop growing. Here most orchids sure do slow down in winter.
Do you think, maybe it's actually warmer in spring and fall when the sun is right overhead?
