Notice of Release of Prairie Harvest Germplasm Common hackberry: selected class of natural germplasm

Abstract

Prairie Harvest Germplasm common hackberry (Celtis occidentalis L. [Ulmaceae]) is a selected class of natural germplasm released for use in conservation plantings in the Northern Great Plains and Upper Midwest of the US. Originating from native trees located in Polk County, northwestern Minnesota, this northern selection is winter hardy with improved form and growth rates. This germplasm release is recommended for conservation use as a tall tree in windbreaks, wildlife areas, and riparian plantings. Prairie Harvest Germplasm represents the first northern source release of common hackberry for conservation use in the northern regions of Minnesota and North Dakota.
