Aruncus

Goat's Beard

When you think of the fringes of a wooded area, think Aruncus. With delicate ivory plumes that make sterling cut flowers, Goat’s Beard is similar to Astilbe, although its sprightly form is more open. A natural beside a pool or stream, this trouble-free perennial favors moist soil, but can handle drier sites and some wind.

<i>Aruncus aethusifolius</i>

Topped by creamy white plumes of minute star-like flowers, fine ultra-chiseled foliage and red-tinged stems shape a tidy dwarf habit that works well as a ground cover around flat stones and rocks. This small gem can also be tucked into the front of the border with broad-leafed Epimediums nearby.

Blooms late May–mid-June

Size: 8" high x 12" wide.

Hardy to zone 5.

<i>Aruncus dioicus</i> ‘Kneiffii’

While the species is a larger perennial hailing from Missouri, this compact, daintier 1889 version sprouts Japanese Maple-shaped leaves, finely hewn with thread-like segments. Sheer cream-colored plumes of minute starry blooms twinkle above the ultrafine deep green hummock. Ideal for gardens short on space plus fresh or dry arrangements, ‘Kneiffii’ can be massed along streams or ponds and in moist shady borders or woodland gardens.

Blooms June–July

Size: 2-1/2' – 3' 0" high x 2' 0" wide.

Zone 3/4.

<i>Aruncus dioicus</i> ‘Zweiweltenkind’

A flurry of large lacy white panicles illuminates the handsome feathered foliage and numerous branching stems. Forging a verdant leafy clump that is shorter and sturdier than the species, this German hybrid dispels all images of a stocky work plant. Its name means “child of two worlds,” and it is indeed otherworldly under tall canopies of Styrax or Maples.

Blooms June–July

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

Hardy to zone 5.

Bred by famed German plantsman Ernest Pagels, this low-growing floriferous cultivar is a cross between the European species Aruncus dioicus and the dwarf Korean native, Aruncus aethusifolius. Crinkled finely cut pinnate greenery cloaks an attractive compact mound, which once established, propels as many as one hundred 12 to 18 in. tall, arching flower stems, plus manages to maintain a trim appearance throughout the season. Staged in a horizontal fashion, petite creamy-white blooms festoon the copious, closely packed short wands, thought by some to resemble feathers, hence the curious namesake.

Blooms June–July

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

Hardy to zone 5.

<i>Aruncus</i> ‘Horatio’

Steeped in elegance, yet remarkably steadfast, this exquisite perennial was bred by noted German nurseryman, Ernest Pagels. ‘Horatio’ is a meticulously crafted cross between Aruncus aethusifolius and Aruncus dioicus, prized for its unique sparkling plumes of tiny cream-colored blooms, which splay out in a horizontal fashion from bronze-tinted upright stems. Fresh green fernlike foliage forms a bushy base beneath the airy star-shaped flowers.

Blooms June–July.

Size: 3' 0" – 3-1/2' high x 2-1/2' wide.

Hardy to zone 4.

Our Featured Plant: Crocosmia ‘Zeal Tan’

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.
