Narrative
In seed production, moderately late maturing, low growing variety. Unique from other bluegrasses in its late emergence from the ground in the spring in seed fields. For unknown reasons, this characteristic does not correlate to late spring greenup in turf. Greens up moderately early in mowed turf. Plants in seed production grow strongly via a lateral rhizome system, but short culm and seedhead length. Lateral growth averages a robust 47 cm from one year's rhizome growth.
