Costco's 3-gallon perennial plants are seasonal in-warehouse garden center offerings that return year after year, providing lasting color and beauty to outdoor landscapes. Sold as an assortment that varies by season and location, these container-grown perennials arrive established and ready to transplant into garden beds, borders, or containers.

Perennials come back each growing season without replanting, making them a cost-effective long-term investment for home gardens. Common varieties available at Costco include flowering perennials such as hydrangeas, salvias, hostas, daylilies, and ornamental grasses, suited for a range of sun exposures from full sun to partial shade. The 3-gallon container size means plants are mature enough to establish quickly and begin performing in the landscape within the same growing season.

These plants attract pollinators including bees, butterflies, and hummingbirds, and are well-suited for planting in perennial borders, pollinator gardens, foundation plantings, and mixed containers. Availability and specific varieties rotate by season and warehouse location.
