Locating Our Plants

The greenhouse and nursery can be found just south of the Graham Visitors Center, directly behind the large greenhouse structure at the south end of the Visitors Center parking lot. From the southeast corner of the Visitors Center Parking Lot, follow the gravel path around the side of a greenhouse structure.

• The Pat Calvert Greenhouse Complex (featuring a Sunhouse and Shadehouse) will be directly in front of you as you curve around the large greenhouse structure.
• The Cloney-Harris Plant Nursery (formerly the Plant Donations Nursery) is just to the southwest of the Greenhouse Complex, next to Arboretum Drive, and can also be accessed via the Visitors Center terrace.

Blue or red price tags only: You’ll see signs to help direct you to the greenhouse and nursery and to identify plants for sale. Select only plants that have red (greenhouse) or blue (nursery) price tags on them! Please do not take plants without those tags, because they might not be ready for purchase!

AT THE NURSERY: A great selection of seasonal perennials, native plants, pollinator plants, and more!
