Canadian Nursery Stock Standard
Canadian Nursery Stock Standard - Ninth Edition (2017)
This ninth edition of the Canadian Nursery Stock Standard (CNSS) continues the purpose established in 1967: standardizing how nursery stock is sized and described, making trade more consistent and efficient. It provides growers, distributors, specifiers, and buyers with clear, minimum specifications using standardized measurements for plant size, relationships between height, width, and calliper, and appropriate root ball or container sizes.
About the Canadian Nursery Stock Standard
What Growers Need to Know
Growers and distributors should ensure that catalogues and contract documents follow the Canadian Nursery Stock Standard. While voluntary, using this Standard helps reduce confusion and conflict in commercial transactions when both parties agree to its use.
This Standard is intended for professional users who understand plant nomenclature and horticultural terminology. It aligns closely with the American Standard (ANSI Z60.1-2014), with metric units used in Canada.
Developed by CNLA with input from industry professionals nationwide, the 2017 edition reflects best practices in nursery production. Always refer to the most up-to-date version at www.cnla.ca
Suggestions for improvement are welcome.
