Narrative
Intended as a replacement for the green needlegrass variety Lodorm (developed by USDA-ARS in Bismarck, ND in 1970) for the Canadian prairies. Selected for improved seedling emergence vs. Lodorm, having an average of 58 seedlings per meter row vs. 18 seedlings/row for Lodorm, from an initial 100 seeds per meter row. More columnar-shaped panicle vs. Lodorm and is more resistant to seed shattering. Good adaptability to western Canadian growing conditions. In all other aspects, similar to other green needlegrass indigenous to the eastern prairie region of western Canada.
