The Volunteer Park Conservatory is a great little flower conservatory. They currently have 3 sections that each feature different types of plants (1 additional section is currently being rennovated and will house ferns).
It is a great place to see several exotic species and beautiful flowers. Some of their orchids appear absolutely perfect. I thought the cactus section was particularly well done, and was impressed with the giant prickly pear cactus tree.
Admission is free, but don't expect to spend more than 20 minutes there.
