Kings Plant Barn is a garden centre at the corner of East Coast Road and Hibiscus Coast Highway in Silverdale, on the Rodney side of Auckland's North Shore. It sells plants, including new-season roses, citrus, hydrangeas and vegetables in pots, along with soils, fertilisers, seeds, tools, pots and garden supplies. Its own range includes compost and sheep pellets, and it also sells home diffusers. Visitors can get gardening advice in store, and the website offers gardening guides and an email list for sales and new arrivals.
