This large, established hydrangea shrub comes in a 15-gallon (56.8-liter) container with a 17-inch pot diameter, making it a mature, ready-to-plant specimen ideal for landscaping, garden borders, or as a striking standalone focal point. The substantial container size means the plant arrives well-rooted and developed, reducing transplant stress and enabling faster establishment in your yard or garden bed.

Hydrangeas are celebrated for their spectacular, globe-shaped flower clusters that bloom in shades ranging from white and cream to vivid pink, blue, or purple depending on the variety and soil pH. Common Costco varieties include Hydrangea macrophylla and Hydrangea paniculata cultivars, which typically bloom from summer through fall. At 15 gallons, this is a premium-sized specimen compared to the smaller 3-gallon or 10-inch pot options Costco also carries, offering immediate visual impact upon planting.

Plant in a location with morning sun and afternoon shade, in well-draining, organically rich soil. Water deeply and consistently, especially during the first growing season. Hydrangeas in large containers benefit from thorough watering to ensure moisture reaches the full root mass before transplanting.
