liner
n.— «Ten years ago, Roger Ruske told growers, Cumberland Nurseries decided to become a supplier of “liners.” Liners is a term for immature plants or trees that are kept for a year. The nursery that grows them then sells them to another, where they are grown to maturity.» —“Growers kick the dirt during county tour” by Joseph P.
