Narrative
Dense, dark green Kentucky bluegrass with improved turf quality performance. In seed production, moderately late maturing, low growing, strongly rhizomatous. Unique from other bluegrasses in its late emergence of foliage from the ground in the spring in seed production fields. Plant grows quite laterally via a strong underground rhizome system but is relatively short in statue and culm height. Lateral growth of rhizomes in one year from a single seedling averages 42 cm. Culm length averages 41 cm and seedheads are a relatively small 6.2 cm in length. Head color slightly purplish white, turning quickly to pale green as it matures. Apomixis of the variety averages 88% but varies from 85% to 95% and above, depending on growing conditions. Most of the variant plants are small, miniature plants, showing up in the vegetative stage. Virtually none of the variant plants are tall, common types.
