This is a good sized room with a wandering path with stonewalls around the outside so many of the plants are growing about waist high beautifully displayed and easy to see and smell. In the center is a stream that runs thru the center of the room. Some of the orchids are growing in trees. There are also many bromeliad I will post some of those pictures here as well.

This glass display case was a beautiful display of small ferns and mosses. There were many arrangements with Orchids as part of the display. Here is one featuring orchids and poinsettia.
