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. The Festuca genus is at its best when given full sun and well-drained soil. Afternoon shade is recommended, however, in the warmest regions of the country. Festucas are valued for their clumping habit and are proven performers in areas with cooler climates. In mild areas they act evergreen, but in cooler areas they should be trimmed back almost to the base either before the onset of winter or in early spring. If division is required, it is best performed in the spring so the divisions have time to root in before the onset of winter.
