Persicaria virginiana var. filiformis
Virginia Knotweed
Virginia Knotweed is from North America, with attractive bright green foliage. The wild variation filiformis has beautiful bronze chevron markings on them and can be quite distinct. Has sprays of tiny red flowers in the summer months. Persicaria are commonly known as knotweeds or smartweeds. Flowers in shades of pink or white appear late in the season on these hardy, herbaceous perennials. They are easy to grow and ideal for boerders or as ground cover. The best flower and leaf colour is achieved when grown in full sun.

Flowering
From Mid Summer TO Late Autumn
Most species of Persicaria are in flower through the summer months between mid summer and late autumn.
Planting Outdoors spring
From Early Spring TO Mid Spring
Plant out in the garden in full sun or partial shade. Whilst they prefer moist soil most will tolerate dry conditions but won't spread so much.
Planting Outdoors autumn
From Mid Autumn TO Late Autumn
Plant out in the garden in full sun or partial shade. Whilst they prefer moist soil most will tolerate dry conditions but won't spread so much.
Propagation by Division
From Late Autumn TO Late Autumn
Propagate by division. Dig up and replant healthy sections every 2 or 3 years to keep in check and avoid the centres of clumps dying out.
