Spring is in the air, and it’s time to carry out those exciting garden plans and projects! Add new life and beauty to your home by buying trees, shrubs, and perennials at our volunteer-run Plant Donations Nursery and Pat Calvert Greenhouse, located next to the Graham Visitors Center.

On Saturday, April 8 the nursery will re-open for the season (April through October), and the greenhouse will be back operating at full capacity. Volunteers will be on-site from 10 a.m. to 2 p.m. to help you with plant selections and share more about these volunteer run plant programs.

Shop when convenient: You can shop anytime the Arboretum is open! New plants are added to the inventory every week throughout the season. You can browse the nursery and greenhouse at your leisure and purchase plants through the Gift Shop in the Visitors Center (Wednesdays to Sundays, 10:15 a.m. to 3:45 p.m.) or via our convenient online checkout system.

Volunteer on-site hours: Our nursery and greenhouse volunteers are very knowledgeable and are happy to help with plant advice and selections, come and see them during their program hours! Throughout the regular season Donations Nursery volunteers will be on-site on Wednesdays, from 10 a.m. to 2 p.m., and Pat Calvert Greenhouse volunteers will be on-site on Tuesdays and Thursdays, from 10 a.m. to noon.

Shop with purpose: Purchases from our nursery and greenhouse help fund core horticulture, environmental education, and volunteer programs at the Arboretum.

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 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 (nursery) or blue (greenhouse) price tags on them! Please do not take plants without those tags, because they might not be ready for purchase!
