Ce qu'on demande souvent

Does it need to be cut back?

Yes, comb out dead foliage in late winter or early spring to keep it tidy.

Will it grow in shade?

It prefers full sun and may lose its blue color or become floppy in shade.

D'où vient le nom

The genus name comes from the Greek words for spiral and hair, referring to the twisted awns on the flowers. The specific epithet means always green.

Bon à savoir

• It is often called blue oat grass because its seed heads resemble cultivated oats.
• The blue color is a waxy coating that helps the plant retain moisture.
• It maintains its color best in full sun.
