You see orchids here that have been added to many areas in which gardeners have done their work and offered for sale by retailers. I know some grow orchids in their homes and the retailers are allowed to ship to those who are interested. I always wonder how orchids grow in the wild because I only see them tied into the crook of trees by someone and not growing without human assistance. Most orchids (I think) are epiphytes and collect water and nutrients from their roots which are just hanging there and not in soil (see image below).
