I'm looking for a specific plant. Where is it located on the grounds?

Specific plants or varieties of plants can be located with assistance from the Arboretum's Plant Records Department. When you arrive at the Arboretum, ask the receptionist for assistance in finding the plant that you are interested in.
Check our Gardening Page for information on the care of a particular plant you are interested in. If you cannot find the information there, contact your local extension service for this information.
We are unable at this time to provide you guidance on where you can purchase a specific plant. To be fair to everyone in the nursery industry, we feel we must provide all the sources for a given plant and we currently lack the resources to be able to do this.
