More Information

Description Boulder 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. Details Botanical 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 Grow Soil: 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.

Not looking good

I planted several Blue Boulder fescue plants in March and April of this year. They look pretty much the same as when I planted them. Maybe they are "sleeping" and will perk up next year but not very optimistic. Other grasses I planted look good even in this drought and heat but not the blue fescue. Dissapointed that it's too late for a replacement.

Hello! Thank you for leaving feedback. When transplanting young plants from a nursery pot to a garden, the plant allocates more energy to root development instead of shoot development (above ground). It's important for them to develop a robust root system so they can absorb the nutrients and water in the soil around them. Then after their root system is more developed, they'll invest in their shoots and flower development. They generally spend their first year growing roots in their new home, in the second year, they have more energy to put into growth; and in the third year, they grow and flower vigorously. We hope this helps. Happy Gardening!

Boulder Blue Fescue

All three arrived in great shape and are thriving as a new addition to our back yard landscaping. Our local garden center expert was concerned the region’s clay earth, combined with abundant rainfall, would result in “wet feet”, so we planted them in raised landscaping along a retaining wall.

nice plants

My plants arrived, very healthy and very well packaged. I was so impressed I placed another order and they arrived the same way. Would definitely recommend to anyone.
