En pot: It grows well in large, deep containers with excellent drainage, though it prefers being in the ground.

Division

Dig up a mature clump in early spring.
Use a sharp spade to divide the root ball into smaller sections.
Replant the divisions immediately in well draining soil.

Group this grass with other Mediterranean plants that appreciate lean soil and intense sun.

Bonnes associations

Lavande d'Angleterre — They share similar needs for full sun and well draining soil.
Rock rose — This shrub provides a nice textural contrast to the fine grass blades.
Rosemary — Both plants thrive in Mediterranean conditions and require minimal water.
