Growing Tips & Maintenace
- Thrives in full sun or light shade in a well-drained soil. Remove dead foliage in the spring. Clumps need to be divided in the spring every 2-3 years to maintain vigour. 'Sapphire' is purportedly one zone hardier, and more disease resistant, than the species.
Additional Notes
- Cool Season Grasses: These grasses do the majority of their growing in early spring and start again when 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.
