What it's good for, and what it isn't

A low, dome-shaped grass with needle-like blue-grey leaves for sunny, dry beds, rock gardens, edging and pots. The blue is strongest in full sun and lean, free-draining soil, and it will not put up with wet, heavy ground. It is short-lived: clumps die out in the centre after two or three years, so lift, divide and replant them in spring.

Watch out for

Clumps die out in the centre after 2-3 years, so plantings turn patchy unless divided regularly. It rots easily in wet, heavy soil, especially in winter. Foliage may brown in humid summer heat and in harsh winters; cut it back in early spring.
