Costco's #2 perennial plants come in a standard #2 nursery container (5.7 liters / 1.5 gallons), a size commonly used for established perennial flowers and plants ready for garden installation. Perennials are plants that return year after year, dying back in winter and re-emerging in spring, making them a long-term investment for home gardens and landscaping.

These plants are well-suited for borders, garden beds, and landscape designs. The #2 container size indicates a mature, established root system that transplants readily and typically blooms the same season as planting. Specific varieties may vary by warehouse location and season, and can include popular garden perennials such as coneflowers, daylilies, hostas, lavender, or ornamental grasses.

Plant in a location with appropriate sunlight for the specific variety. Water thoroughly after planting and maintain consistent moisture during the establishment period. Amend soil with compost as needed and follow spacing guidelines for the specific plant variety.
