Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:
Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:

DescriptionBoulder Blue blue fescue (Festuca glauca) is one of the bluest ornamental grasses on the market! The steel-blue, almost metallic foliage adds a refreshing contrast to typical green-hued plants. The colors never fade, even during spouts of intense heat and drought.
Did we mention how durable and low maintenance it is? This hardy, perennial grass thrives in almost any garden condition! The compact habit makes it the perfect addition to any sunny spot in your garden. We particularly love it in patio containers.DetailsBotanical name:Festuca glauca 'Boulder Blue' Common name: Bolder blue fescue Zone: 4 - 9 Sun exposure: Sun (> 6 hours sun) to part-sun (4-6 hours sun) Height x width: 12" x 12" Flower color: Light beige Foliage color: Steel-blue Season of interest: Spring through fall Bloom time: Summer Features: Space savers, rain gardens, rabbit resistant, ground covers, drought tolerant, container plants, cold tolerant, best sellers, best for beginners Uses: Container gardening, cottage gardening, edging, ground cover, massing, ornamental
How To GrowSoil: Happy in average soils. It is highly tolerant of urban pollution and will even thrive in inner-city environments. Light: Sun (> 6 hours sun) to part-sun (4-6 hours sun), but the best colors develop with more sun. Water: It prefers average to dry locations and dislikes excessive moisture. Spacing: 18 inches Fertilizing: We don't recommend fertilizing them their first spring to promote root development. It can be fertilized subsequent years in early spring with balanced fertilizer but is generally unnecessary. Winterizing: No specific care is needed—no need to cut back for winter. Maintenance & pruning: "Rake out" with rake or fingers all spent foliage in early spring before it resumes active growth for the season. Division should be done in spring every few years to keep Festuca at its best.

Boulder Blue Fescue
I am so happy with the plants and this company. I ordered 22 plants, one arrived too sad to plant, and three others are struggling with this summer's heat and drought. I contacted Great Gardens yesterday, and arrangements have already been made for four replacements to be shipped. These little guys are thriving in the worst possible soil...
