A RECENT HISTORY OF CHANGING TRENDS IN USA GARDEN ROSE PLANT SALES, TYPES, AND PRODUCTION METHODS
Nursery crop sales have steadily increased in the USA for the last several decades. Despite this fact, the total number and value of garden rose plants sold in the USA has been decreasing since the 1980s. Garden rose is the generic term referring to roses that are used outdoors as opposed to pot roses (disposable flowering potted plants) and cut roses (florist roses). A segment of garden roses commonly referred to as landscape roses has played an increasing role in production and sales in the past two decades. Due to the introduction and increasing popularity of landscape rose cultivars, sales of garden roses have stabilized in more recent years. Disease tolerant landscape type roses, such as Simplicity®, Knock Out® and others like them, have grown in popularity with USA landscapers and the consuming public. Concomitant with the rise of landscape rose sales has been a change in the method of production. The use of rooted cuttings, commonly referred to as liners or plugs, for own-root container nursery and field production of garden rose plants has risen dramatically while the production of field-grown grafted plants has fallen. Characteristics of landscape roses and changes in production methods tailored to this type of rose vs. those for field-grown grafted rose plants are discussed.
