It’s a classic for a reason. Probably the most well-known ornamental fescue, ‘Elijah Blue’ sports silvery-blue foliage that forms a small, dense mound. Puffy, buff-toned flower spikes reach a foot above the foliage. The plant stays a foot or under and spreads even less. ‘Elijah Blue’ prefers full to partial sun. It will tolerate a light shade, but you’ll see the best foliage color in sunnier spots. It is hardy in Zones 4 to 8 and provides lovely winter color in milder areas – harsher winters may cause considerable browning. This fescue is ideal for edges, borders or accents. Great for rock gardens and pairs well with other ornamental grasses. Plant just 8 to 10 inches apart for the best effect and to prevent weeds from sneaking in between plants. Quick Culture Tips Plant one 50-cell liner per 1 gallon pot for finished plants in eight to 10 weeks for spring sales. Pot with good root/soil contact – ensure pots have no air pockets. Media: Choose a well-draining commercial media. ‘Blue Elijah’ prefers loose soil. Temperature: Maintain greenhouse temperatures at 65 to 75° F during the day and 55 to 65° F at night. pH: Aim for soil pH levels approximately 5.8 to 6.2. EC: Soil electrical conductivity (EC) should be between 1.8 and 2.2 mS/cm using the 2:1 extraction method. Fertilizer: Provide a constant liquid feed at medium levels of 150 to 200 ppm nitrogen in a balanced fertilizer. Moisture: Grow plants on the dry side. Pest and Disease: Drench with fungicide after transplant as a preventive measure. Scout and monitor regularly. With good ventilation and sanitation, typically ‘Blue Elijah’ experiences no significant pest or disease issues.
