They look so sad with their heads hanging down looking at the ground

There's rarer ones like in the family, like gnome plant and hypotytis, and the famous snow plant. Fun fact orchids are partial mycoheterotrophs, and some species have become much the same way as these plants, lost all its chlorophyll, the sad thing is mycoheterotph in general are quite rare, as their associated with specific fungus and environment. I think the Chinese have managed to cultivate one species of gastrodia orchid( full mycoheterotroph), the others are very rare species, and a lot are recently discovered, because they don't show up every year
