Persicaria Capitata

 

Pinkhead Smartweed

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. P. capitata is a mat-forming, stem-rooting, deciduous or evergreen perennial with green leaves, each with a maroon, v-shaped mark. It bears dense, rounded panicles of bell-shaped, pink flowers in summer.

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.
