Calamagrostis

Extremely tough, undemanding and hardy, this truly all-purpose grass brings bold, erect lines to the garden spectrum.

<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.

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.

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.

The ultrafine white hairs lining arching medium green blades glisten with dew, while narrow, loosely feathered caramel-colored inflorescences loll above. Smaller-sized than C. 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 en masse around large shrubs or small trees and looks especially lovely skirting a Japanese Maple.

Blooms August–October

Size: 3' 0" – 4' 0" high x 3' 0" – 4' 0" wide.

Hardy to zone 5.

Garnished by violet tinges, low loose mounds of glaucous blue-gray blades generally remain throughout the year and set this cool season California native apart from other North American Calamagrostis species. Slender tapering pinkish purple panicles sojourn just above the relaxed foliage in a lovely 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.

Our featured plant: Achillea 'Hella Glashoff'

Amazing Achilleas, Invigorate your summer plantings!

Amazing Achilleas…. These sturdy, dependable perennials produce small indivdual blooms that populate broad, flat flower heads, lending welcome horizontal elements to any garden bed. Ideal for bouquets, fresh or dried, the long-lasting blossoms range in color from alabaster to soft yellow and gold, as well as terracotta, pink and sassy red. Cut back their flowers in midsummer and enjoy a fall encore! Spicy scented, attractive fern-like green or gray-tinged foliage cloaks their strong straight stems. Slowly spreading and somewhat drought tolerant, Yarrow seem to thrive on neglect. They can handle low soil fertility plus coastal wind and salt spray. Be sure to check out our diverse on-line Achillea selections!

Invigorate your summer plantings.… A few simple maintenance techniques will help plants appear fresh throughout the upcoming dog days of summer. The addition of a chipped bark mulch or well-rotted compost, applied as a top-dressing, not only reduces water requirements, but generally makes it easier for plants to maintain perky looking leaves and vigorous habits. A July or early August trimming of long-blooming perennials, such as Nepetas and most Geraniums ensures myriad flowers that will keep on coming ‘til the first frost. Featured in this newsletter, you’ll find the fabulous plants that caught my eye as Boobah and I took our morning walk through the nursery and adjacent display borders this past week. Hopefully, you’ll have room to ensconce several of them in a well-traveled spot. Happy Digging!
