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. View a slideshow of plant images from this genus
Himalayan Fleeceflower
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 affinis ‘Dimity’ (P-0250)

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’. Zone 5/6.

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. Zone 5/6.

Red Dragon Persicaria
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.
