Last year’s multiple-day Arboretum Fall Plant Sale was a big success, so we are continuing with the same format for 2023. The sale will run for three weeks, from September 9 to 30. Customers will be able to select their plants from our greenhouse and nursery and check out either onsite (during gift shop hours) or online.
The Pat Calvert Greenhouse is open whenever the park is open—dawn to dusk. You are welcome to browse their selections at your leisure. Our helpful volunteers will be onsite at select hours (see below) to help you with plant selection.
Two ways to pay: 1) At any time using our new online checkout system; instructions below. 2) At the Arboretum Gift Shop, open in the Visitors Center from Tuesday to Sunday, 10:00 a.m. to 4:00 p.m. NOTE: The Gift Shop is still operating card and check only; we are not carrying cash.
Questions? Please contact info@arboretumfoundation.org or 206-325-4510.

Knowledgeable Plant People—Onsite Hours
The volunteers who run our greenhouse and nursery programs love to share their knowledge of plants and are ready to help! During the sale, volunteers will be on-site and available to answer questions during the following times:
Greenhouse volunteers: Tuesdays and Thursdays, from 10 a.m. to 12 p.m.
Nursery volunteers: Wednesdays, from 10 a.m. to 2 p.m.
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!
