Persicaria (Knotweed)
at Digging Dog

Including Persicaria varieties Rosea, Inverleith, Superba, Blackfield, and Fat Domino

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.

Persicaria affinis ‘Dimity’  full sun  partial shade
Himalayan Fleeceflower
Persicaria affinis 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' wide; hardy to zone 3.

Persicaria amplexicaulis ‘Fat Domino’  full sun  partial shade

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 long blooming flowers, this strong growing Persicaria can be positioned right up front and superimposed against white flowering Nicotiana sylvestris, where it easily turns heads until the seasonís end.

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 launches an irresistible flood of long blooming slim 4 in. tall, orange-red tails. ‘Orange field’ can be positioned in the mixed border, where its exhilarating shades meld with Salvia confertiflora or bring a lift to white Hydrangeas, Phlox, Helianthus and blue flowering Salvias.

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.

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.

Persicaria microcephala ‘Red Dragon’  full sun  partial shade
Red Dragon Persicaria
Persicaria microcephala Red Dragon Persicaria microcephala 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'–4' high x 4' wide; hardy to zone 5.
