Growing & Maintenance Tips
This is an aggressive grass, by rhizome and by seed. Perfect for parking lot medians, because of its salt-tolerance. . . Grows best in a moist to dry soil, in full sun to partial shade and is a highly adaptable grass. Foliage can be left for winter interest, but prune (if desired) in early spring to make way for new growth.
Notes
Cool Season Grasses: These grasses do the majority of their growing in early spring and continue until temperatures start to cool in the fall. During the warmer summer months, they stop growing and some will even go dormant. Cool season grasses flower in the spring or early summer. Most cool season grasses grow best in a consistently moist soil.
