The nice thing about a botanical garden is that you can return many times and see something different, depending on the time of year. I visited this place over two years ago, but still enjoyed my visit today. I don't know the names of all the plants, so I am just going to post them all without comment.
The important thing to know is that this garden specialized in orchids and other epiphytes or plants that grow on other plants. http://selby.org/about/
