I was going to say that looks like a Bletilla (Chinese Ground Orchid) to me, but when I opened one of my books to check, right above it is another orchid that looks very similar called a Bletia which is endemic to the American Tropics. Both have pink flowers, although I also have the alba Bletilla. Someone familiar with both is probably needed to tell which it is as foliage is not really shown, however the white in the lip looks more like Bletilla to me. These grow outside easily in our climate in NZ and lose their leaves for the winter. Flowering is in spring following the leaves appearing. Mine will be in flower shortly as the leaves have started growing.
