Calamagrostis

Extremely durable, undemanding and hearty, this all-purpose clump-forming grass delivers arresting accents to any garden setting.

<i>Calamagrostis</i> x <i>acutiflora</i> ‘Avalanche’

This distinctive newcomer is a variegated form of Calamagrostis ‘Karl Foerster’ first spotted by Steve Schmidt at American Ornamental Perennials. Showcasing dramatically striped foliage, the medium-sized clumps spring to life as a hefty white central band bordered by narrow green margins embellishes each blade. Topped with an airy aura of rose-tinged green plumes that later take on warm, golden hues, ‘Avalanche’s straight-up stance forges a compelling specimen, or when planted en masse, a boldly patterned screen. (PPAF)

Blooms May–January

Size: 5' 0" high x 3' 0" wide.

Zone 4/5.

Chanced upon at Garden Gate Growers in Kettle Falls, Washington, this flashy variegated form of ‘Karl Foerster’ wields slender deep green blades heightened by a central golden stripe. The long, narrow vertical plumes are somewhat more open compared to ‘Karl Foerster’s, exhibiting a gossamer-like quality that unfurls in muted mauve tones and ends the season with warm wheat shades atop staunch honey-colored stalks. Triumphant over deer, heavy clay and hot weather, ‘Eldorado’ enjoys sunny, moderately moist environs, while its robust eye-catching profile can be utilized as a straight-standing specimen or planted en masse. (pp#16,486)

Blooms May–December

Size: 5' 0" high x 2' 0" – 2-1/2' wide.

Hardy to zone 4.

<i>Calamagrostis</i> x <i>acutiflora</i> ‘Karl Foerster’ <i>Calamagrostis</i> x <i>acutiflora</i> ‘Karl Foerster’

Named for pioneering German nurseryman Karl Foerster, this selection bears loose and airy 12 in. seed heads, which tighten to slender plumes by midsummer. Rising above 2 ft. clumps of narrow green foliage, the inflorescences create an ideal semitransparent veiling effect. Plant with deep green Viburnums to accentuate its golden flowering stems.

Blooms May–January

Size: 5' 0" high x 3' 0" wide.

Hardy to zone 5.

This exceptional new Asian denizen is a vigorous, upright clumping grass. Bleached to a luminous white when mature, sizable, fluffy mulled pink plumes sway above dapper, glossy green blades that are broader and somewhat more coarsely textured than Calamagrostis ‘Karl Foerster’s foliage. Bestowing late summer blooms and shapely good looks throughout the season, Caspian’s undemanding habit provides butter-yellow fall foliage, craves adequate moisture and tolerates light shade plus a range of sites.

Blooms August–November

Size: 4' 0" high x 2' 0" wide.

Hardy to zone 4.

Overdam is a choice new variegated selection of our favorite vertical accent plant, Calamagrostis. Its a bit smaller and more refinded than its parent, enabling Overdam to fit well in the intimate garden, or by a pool or patio. Golden inflorescences tower almost 3 ft. above tufted 15 in. clumps of foliage striped green and white with a blush of pink.

Blooms July–November

Size: 4' 0" high x 2' 0" wide.

Hardy to zone 5.

Warmed by rosy maroon plumes, Calamagrostis brachytricha is native to the moist woodlands of eastern Asia. The inflorescences stay open and feathery, even when they dry, and eventually pale to an elegant silvery gray. Magical both in an arrangement or outside when the wind blows, the panicles leap from a clump of glossy green, upright and arching blades. This warm season grass exhibits a smaller stature, making it well suited for a container.

Blooms September

Size: 4' 0" high x 2' 0" wide.

Hardy to zone 4.

<i>Calamagrostis</i> x ‘Cheju-do’

The minute white hairs lining arching medium green blades glisten with dew, while narrow, loosely feathered caramel-colored inflorescences loll above. Not as tall as Calamagrostis x ‘Karl Foerster’ and well-suited for gardens short on space, this relatively new soft-looking Calamagrostis develops a versatile low maintenance clump that transmutes warm rosy amber hues in autumn. ‘Cheju-do’ can be featured as an elegant specimen, planted in drifts around large shrubs or small trees and is especially lovely skirting a Japanese Maple.

Blooms August–October

Size: 2' 0" – 3' 0" high x 2' 0" – 3' 0" wide.

Hardy to zone 5.

<i>Calamagrostis foliosa</i> <i>Calamagrostis foliosa</i>

Garnished by violet tinges, low loose mounds of glaucous blue-gray blades generally remain evergreen throughout the year and set this California native apart from other North American Calamagrostis species. Slender, tapering pinkish purple panicles sojourn just above the relaxed foliage in a comely fountain-like fashion and by early summer adopt luminous flaxen hues. Cape Mendocino Reed Grass pouts when it’s hot, appreciates summer irrigation and looks artful either as a large-scale ground cover or peppered throughout mixed borders and naturalized meadows.

 

Blooms May–November

Size: 18" high x 2' 0" wide.

Hardy to zone 8.

Captivating Crocosmias, Plants that Dodge to Dog Days of Summer, 2020 T-shirst have arrived!

Captivating Crocosmias!

Crocosmias boast a bounty of late summer color as our gardens transition into autumn. Displayed on the ends of gracefully arching spikes above winsome sword-like leaves, the clustered tubular flowers range from yellow, peach and orange to fire-engine red. The prismatic tones meld well with white-flowering Hydrangeas and perennials such as Selinium wallichianum, Actaea simplex 'Atropurpurea', Alcea 'Polarstar' or Aster 'Bridal Veil'. The yellow and melon shades sparkle amid the blue blossoms of Aconitum, Caryopteris 'Longwood Blue', Perovskia 'Blue Steel' and  Aster 'Little Carlow'. For sizzling fun you could create a hot border, intermingling them with Kniphofia 'Bee's Sunset', Helenium 'Potter's Wheel' or Helianthemum 'Fire Dragon'. Be sure to add some to your next cut arrangement!

Commonly known as Montbretia, they do their best when provided with good drainage, moderate moisture and some protection from hot afternoon sun. Please feel free to check out our extensive collection of Crocosmia cultivars in the perennial section of our online catalog.

Dodge the Dog Days of summer….

with plants that pack a punch of blooms and alluring leaves at this time of year. By late August, our borders can look a tad tired and may be in need of some sprucing up. Adequate moisture and an additional application of compost will ensure late summer vitality. You can trim perennials, such as Nepetas and Geraniums, and savor their fresh new growth plus a flourish of blooms, often until the first frost! We hope some of the plants featured in this newsletter lift your spirits and maybe even inspire a little awe as summer wanes. 

All of us Digging Dog plant wranglers wish you Happy Digging and good health.
