The NPS Description of Terms provides detailed guidance on how to accurately specify planting material with clearly illustrated definitions and descriptions of the terminology and is free to view at www.CSDhub.com
Information is arranged by defined plant groups:
Each Plant Group includes relevant descriptive information for specifying that plant type. Some terms and descriptions are common across plant groups (e.g. Name).
Some terms and descriptions are applicable only to one/a few of the plant groups (e.g. Canes/Framework).
