Ajuga reptans 'Black Scallop' Ajuga reptans 'Black Scallop'
('Black Scallop' bugleweed)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Black foliage and spiky blue flowers (which appear in early summer) make a dramatic contrast. 'Black Scallop' thrives in full sun, which intensifies the black color. In full sun, the plant produces numerous runners, which should be thinned to prevent crown rot. In large plantings, you can run a rotary mower with a bagger attachment over the patch to control crowding and keep the foliage fresh. In mixed container plantings, the spilling habit of the plant makes it a standout choice. -Ron Smith, Regional Picks: Upper Plains, Fine Gardening issue #120

Anemone blanda Anemone blanda
(Grecian windflower)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This plant produces a great low-growing mat of flowers. The cheerful starlike blossoms come in pink, blue, and white, and the attractive finely cut leaves disappear soon after flowering.

Campanula poscharskyana 'Blue Waterfall' Campanula poscharskyana 'Blue Waterfall'
(Serbian bellflower)
(3 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Serbian bellflowers have an easy, undemanding habit. Creating a stream of lavender blue, the 1-inch-diameter star-shaped blossoms bloom reliably from late spring to early fall. The foliage remains evergreen in mild winters and needs to be sheared only once in a while to keep its appearance tidy. 'Blue Waterfall' flows beautifully along bed edges and through rock gardens in full sun to partial shade.

This variety has fragrant, deep blue, cornucopia-shaped flowers carried tightly on red stems above 6-inch tall, blue-green foliage. It is considered one of the best blue forms for color and performance.

(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

From late spring to summer, this species produces clusters of brilliant blue flowers over ferny foliage. It is the parent of many of the rapidly expanding selection of choice blue cultivars.

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

The first of the coveted blue corydalises to be introduced, it produces fragrant clusters of long-spurred, azure flowers on a compact plant.

Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This choice corydalis produces fragrant clusters of periwinkle-blue flowers and ferny foliage infused with purple hues. It is similar to 'Blue Panda,' yet is slower to spread and blooms more reliably during the summer.

Festuca glauca 'Boulder Blue' Festuca glauca 'Boulder Blue'
(Blue fescue, Gray fescue)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Regarded by some as the bluest blue fescue, this plant forms compact, cascading mounds of foot-tall, intensely blue, narrow leaves that are attractive in all seasons. Blooms are generally secondary to the foliage, but this cultivar blooms more heavily than most, with spikelets in summer. This cultivar is long-lived and very hardy. Grow in groups in a border or rock garden, or as a groundcover. 

Festuca glauca 'Elijah Blue' Festuca glauca 'Elijah Blue'
(Blue fescue, Gray fescue)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

These compact tufts of 8-inch-long powder-blue leaves are well suited for edging and naturalizing in the rock garden. 

Geranium pratense 'Midnight Reiter' Geranium pratense 'Midnight Reiter'
(Meadow cranesbill)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Deeply cut plum-purple leaves emerge in spring and stay true to color throughout the season. Lavender-blue flowers bloom beginning in late spring. 'Midnight Reiter' grows to only about 6 or 8 inches tall and twice as wide. More shade causes the foliage to be greener.

Phlox divaricata 'Clouds of Perfume' Phlox divaricata 'Clouds of Perfume'
(Blue phlox, Wild sweet William, Woodland phlox)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This is a very fragrant native woodland phlox with powder-blue flowers in spring. Reaching only 1 foot tall, it can spread to almost 2 feet and makes an attractive groundcover under shrubs or planted with other spring-blooming wildflowers. Leaves are semi-evergreen and hairy; stems root along their length. The blue flowers are salverform with petal lobes. This plant attracts hummingbirds and butterflies.

Pulmonaria 'Silver Shimmers' Pulmonaria 'Silver Shimmers'
('Silver Shimmers' lungwort)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This eye-catching perennial has silver-plated leaves with speckled margins. Its blooms are among the largest of all lungworts, beginning as pink buds and opening in early spring to display platinum blue flowers.

This plant will eventually form a decent-sized mound that resembles a mountain of liquid silver. It's perfect in a woodland border and makes a great ground cover and container plant. In mild winters, its leaves may stay evergreen.

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This cheerful, reliable plant brings a nice touch of color to the garden in spring. The leaves are pointed and hairy and splattered with silvery blotches. As the plant grows, the leaves overlap, creating a swirly pattern. In spring, clusters of silky pink flowers appear. They fade to a soft blue that harmonizes well with the leaf color. -Sue Whetten, Regional Picks: Rocky Mountains, Fine Gardening issue #127

A hardy, fast-growing evergreen shrub, creeping rosemary has a prostrate habit and attractive flowers and fragrance. Dark green leaves, to 2 inches long, are rich in aromatic oils and commonly used as a culinary herb. This plant is loved for its strong pinelike flavor and fragrance.

Vinca minor 'Illumination' Vinca minor 'Illumination'
(Common periwinkle, creeping myrtle)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Like other creeping myrtles, 'Illumination' is a tough evergreen ground cover for shade that will grow in almost any soil. Its hallmark is its bright gold leaves that are edged with a border of irregular green. Periwinkle-blue flowers appear in spring. Use 'Illumination' as a shade ground cover or in hanging baskets. -Tom Nelson, Regional Picks: Northern California, Fine Gardening issue #127

Creeping myrtle is a fast-spreading, 4- to 8-inch-tall, evergreen groundcover with shiny green leaves borne in pairs on long, arching stems. Star-like, 1-inch-wide blue flowers bloom for one month in spring. Cultivars include 'Bowles,' which blooms sporadically throughout the growing season, and variegated vinca, with creamy white-and-green leaves.

Viola ‘Etain’ Viola ‘Etain’
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

A hardworking, compact perennial, ‘Etain’ violet forms well-behaved clumps and blooms from time to time from spring through fall. The attractive, fleshy, bright green foliage needs protection from slugs. -Sylvia Matlock, Regional Picks: Northwest, Fine Gardening issue #127
