Soft powdery blue, spiky foliage that keeps its color all year round makes this grass a top pick. One of the more durable and longer-lived varieties, 'Elijah Blue' is a small, clumping grass with a rounded habit. In early summer, wheat-like seed heads are produced on tall, spikey stalks in great numbers. Prefering dryer conditions, this is the perfect grass for rock gardens, in stone troughs or pots, for costal climates, or even for use as edging.
