Anderzhon Nursery Sales has several suppliers for perennials and grasses. Most of these are grown in 1 or 2 gallon size, but we do occasionally have grasses as large as 5 and 7 gallons. We also occasionally deal in quarts or smaller, but the overwhelming majority of our business in this area are #1's. One of our suppliers, Scarff's Nursery in Ohio, does a fantastic job with 2 gallon perennials at a great price. Just let us know what you're looking for and we'll help you out.
