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
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.

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... Ozark clay gravel.Two rows are already softening a concrete retaining wall.

Boulder Blue Fescue

It has been insane miserably hot but these guys are thriving. Easy on the water even in 100+ temp. Saw a little browning but trimmed & they are beautiful & growing. I'm so anxious to see them really expload but in a few short months I can see noticeable progress. I paired these with the Dolce Wildberry Coral Bells. The Blues are circling the Bells with a red mulch looks great! Great Garden really is a great nursery

Poor growth

All three of our plants are still alive but don’t look good at all.

Hello! Thank you for leaving a review. This time of year it is so important that your new plants receive enough water. Watering tends to be one of the most common problems for new plants, since they need more water than the mature plants in your garden.

It's hard to say for certain why you're not seeing growth in your new plants since so many factors like weather, soil type, watering, and fertilizing all come into play. Perhaps you're familiar with the old saying about plants: first year sleep, second year creep, third year leap. This applies to plants in the garden center as well as plants you purchase online. They generally spend their first year growing roots in their new home, the second year they have more energy to put into growth, and the third year, they are growing vigorously.

We do offer at 60-day guarantee on all of our plants! If your plants appear to be dying, please send photos of them to claims@greatgardenplants.com, making sure to put your order number and name in the subject line so that we may provide the best assistance possible. If you received your order within 60 days, we will happily refund your purchase or send replacements. Happy Gardening!

Very Blue!

Arrived in quality packaging a year ago. They've grown beautifully in a full-sun area in North Texas.
The best part? They're actually blue! Very pretty accent plants that survive high heat, drought, and multiple freezes. They are real landscape standouts!
