I grew up in Pittsburgh, where I loved going to the Conservatory. It had a fabulous collection of different plants from around the world.\r

The Columbus one is horribly disappointing to someone who has seen a real conservatory. Columbus has almost no rare plants. It's just a larger version of a good nursery like Oakland Nursery. They have a few large plants that you would not see at a nursery, but otherwise, go to your local garden center, and it's free.
