These orchids were in the "Cool House" - pretty much the opposite of a green house. See, if you live in Singapore - it's hot all the time, and you have to make a house to keep the plants that grow up in the mountains. These are orchids that grow on trees up in the mountains. Did you know that? Orchids grow on trees, well, not like it's an Orchid Tree, or anything, just a tree, that has orchids growing on the trunk - does that make sense?
