Persicaria

Knotweed

Poor Persicaria! Certain weedy, invasive members of the genus have given the rest a bad name, and discouraged gardeners from getting to know these versatile performers. Our garden-worthy selections are happiest in semishade with ample moisture.

<i>Persicaria affinis</i> ‘Dimity’

The deep green leaves of this graceful ground cover turn a rich brown during the winter and form a thick mat over a few seasons. The jointed, wine-red stems pick up the accents in the white and crimson flowers which are arranged, lavenderlike, along dense 2 to 3 in. terminal spikes held over a foot above the foliage. As the blooms mature, they darken to a crimson-rose shade, and finally end their days colored a rich rusty brown.

Blooms late May–September.

Size: 18" high x 3' 0" wide.

Hardy to zone 3.

<i>Persicaria amplexicaulis</i> ‘Fat Domino’

Evolving from a 2002 Belgian breeding program, ‘Fat Domino’s bushy rich green foundation hosts a rubescent surge of long chubby, dark red racemes that don purplish overtones. Dashing, large pointed textural leaves are loosely arranged on numerous staunch, upright jointed stems. With a reliable saucy stance plus sumptuous enduring flowers, this strong growing Persicaria can be positioned right up front and superimposed against white-flowering Verbascum ‘White Domino’, where it easily turns heads until the season’s end.

Blooms August-October

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

Zone 5/6.

Persicaria amplexicaulis ‘Alba’ (P-1675)

Each $8.75

AVAILABLE LATE FALL 2019

Legions of slim white fleecy tapers, cresting tall straight stalks, promote cool floral accents for a hot summer day. Enhanced by prominent midribs, wavy margins and cordate bases, the large pointed matte green leaves fashion an attractive upright bushy clump that doesn’t spread and looks classy, especially when coupled with other snowy bloomers such as Astilbe ‘Ellie’ and Aster ‘White Lovely’.

Blooms August – October.

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

Zone 5/6.

<i>Persicaria amplexicaulis</i> ‘Atrosanguinea’

Named for its rosy red, Bottlebrush-like flower spikes, which hover above broad green leaves, ‘Atrosanguinea’ combines well with Panicum ‘Prairie Sky’ and Anemone ‘Andrea Atkinson’.

Blooms August–October.

Size: 4' 0" high x 0" & spreading wide.

Zone 5/6.

Raised by Chris Ghyselen, the Belgian who introduced ‘Fat Domino’, this long-flowering must-have Persicaria bears frisky black-tipped tapers, parading dark unopened buds and deep dusky red flowers. The full-toned blooms make a splendid spectacle above energetic flowing mounds of bold lance-shaped leaves that greet autumn with buttery yellow hues.

Blooms August|ndash;October

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

Zone 5/6.

Persicaria amplexicaulis ‘Golden Arrow’ (P-1422)

Each $8.50

AVAILABLE LATE SEPTEMBER 2019

These lance-shaped gold-infused green leaves promise to perk up the darker recesses of your landscape. Perched over a bright leafy mass, narrow tassel-like spiky flowers create an irresistible splash of vibrant cardinal-red accents.

Blooms August|#8211;October

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

Hardy to zone 4.

<i>Persicaria amplexicaulis</i> ‘Inverleith’

A leafy dwarf form of Persicaria amplexicaulis, this low growing cultivar has narrow foliage, crimson tapers and a refined appearance. It makes a perfect understory for late blooming Hydrangea ‘Unique’.

Blooms August–October.

Size: 18" high x 0" & spreading wide.

Zone 5/6.

Persicaria amplexicaulis ‘Orange field’ (P-1708)

Each $8.75

AVAILABLE SEPTEMBER 2019

<i>Persicaria amplexicaulis</i> ‘Orange field’

A mainstay for bridging the gap between summer and fall, this new Belgian introduction imparts vertical late season color over lusty foliage. Green spear-headed leaves compose a big bushy base that propels an irresistible flood of long-lasting, slim 4 in. tall, coral and scarlet-hued tails. Ensconce |lsquo;Orange Field|rsquo; in the mixed border, where its exhilarating shades either meld with Salvia confertiflora or bring a lift to white Hydrangeas, Phlox, Helianthus and blue-flowering Salvias.

Blooms August–October

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

Zone 5/6.

In an elegant presentation, ‘Rosea’ offers 4 to 5 in. long flowers—slender and softly pink tapers—borne on tall stems. Its lush, prominently veined foliage turns a vibrant yellow in fall.

Blooms August–October.

Size: 4' 0" high x 0" & spreading wide.

Zone 5/6.

Persicaria amplexicaulis ‘Summer Dance’ (P-1312)

Each $8.25

AVAILABLE WINTER 2019

With foliage that’s close to lime-green, and spiky floral tails that approach the scarlet spectrum of rosy pink, this slow spreading perennial is sure to please.

We brought ‘Summer Dance’ home from Piet Oudolf’s Dutch nursery and have come to appreciate its brighter, less rambunctious nature. Swaying to a late summer breeze, our stand lives up to its name while cheerfully commingling amid Anemone ‘Andrea Atkinson’ in the border.

Blooms August–November.

Size: 3' 0" high x 0" & spreading wide.

Zone 5/6.

Zesty rose-madder colors imbue the densely packed rotund tapers of this steadfast Blooms of Bressingham introduction. Perfect for arrangements and championed as richer and fuller than most Persicarias, the vivacious long-blooming flowers prance above a carefree mound of medium green triangular leaves. Intermingle ‘Taurus’ with Eupatorium purpureum, Aster ‘Blue Danube’ and Helianthus ‘Lemon Queen’, and a pleasing late season medley is yours to enjoy. (pp#9682)

Blooms August|#8211;October

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

Zone 5/6.

Above low-lying large Dock-like green leaves with undulating margins, the firm upright branching stems release a fluffy floral pageant of plump, dense-set bright pink pokers. This hearty AGM winner grows as a handsome easy-care ground cover, emphasizing jubilant blooms that are more vividly colored and a bit later plus a tad smaller than its similar sister ‘Superba’. Prized by butterflies and flower arrangers, ‘Hohe Tatra’ effectively knits together shrubs and taller perennials in an adequately moist mixed border.

Blooms May–July

Size: 18" – 2' 0" high x 2' 0" wide.

Hardy to zone 4.

<i>Persicaria bistorta</i> ‘Superba’

Copious crepe paper-like dark green leaves in curly festoons decorate the base of these showy and long-lasting 4 to 5 in. spikes of dense pale pink flowers. This Persicaria is perfect for cutting and admirable in the border with Digitalis ‘Snow Thimble’, while its clump-forming base can easily be divided every few years.

Blooms April|#8211;June

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

Hardy to zone 4.

<i>Persicaria microcephala</i> ‘Red Dragon’ <i>Persicaria microcephala</i> ‘Red Dragon’

Darkly alluring, this sumptuous perennial has plenty of reason to be “big headed,” so we find the epithet microcephala a somewhat dubious observation. Each spring, deep red shoots emerge and lift themselves into a graceful arching form. Velvety leaves of a rich burgundy purple are dramatically marked with lance-shaped mint-green and silver chevrons, and later in the season are topped with delicate white flowers.

Visually arresting anywhere, plant ‘Red Dragon’ in a container or in the garden and let its gemlike elegance be set off by bright-leafed Spiraea ‘Magic Carpet’. It prefers moist soil, but can adapt to drier conditions.(PP# 12,062)

Blooms August–September.

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

Hardy to zone 5.

Our featured plant: Crocosmia x crocosmiiflora ‘Honey Angels’

Colorful Crocosmias, Be Awed by your August garden, Saturday Strolls!

Colorful Crocosmias!

Crocosmias pack a punch of late summer color as our gardens transition into autumn. Their clustered tubular flowers populate the ends of gracefully arching spikes, which emerge from handsome sword-like foliage. Ranging from yellow, peach and orange to fiery red, their prismatic shades look exceptional with white flowering perennials such as Phlox ‘David’, Selinum wallichianum and Aster ‘Bridal Veil’, as well as the blue blossoms of Aconitum, Agapanthus ‘Storm Cloud’ or Aster ‘Twilight’. For fun you could create a hot border, blending them with Kniphofia, Helenium, Salvia and even other Crocosmia, plus be sure to include some in your next bouquet. Commonly referred to as Montbretia and hardy to Zone 6, they appreciate, good drainage, adequate water and some shade in scorching summer sun. Please feel free to check out our extensive collection of Crocosmia cultivars in the perennial section of our online catalog.

YES, it’s possible to be in awe of your late August garden….

At this point in the season, some areas in our gardens may appear a tad worn or lackluster. If you haven’t already done so, you may wish to cut back a few tired looking perennials, such as the Nepetas or Geraniums, so you can enjoy a fresh flourish of growth plus more blooms. Adequate moisture and an additional application of compost will also ensure late summer vigor. Incorporating plants that provide a bounty of flowers and alluring leaves in August and September helps buoy our spirits, and hopefully even inspire a little awe as we approach fall. Though the plants featured in this newsletter either promote a bold statement or possess more refined aspects, they equally caught my eye and made me pause to take a closer look. Perhaps they’ll spark a wondrous moment for you as well. All of us Digging Dog plant wranglers wish you Happy Digging!
