Persicaria

(formally called Polygonum)

Common Names: Bistort, Fleece Flower.

Moisture loving plants with creeping stems and bottle brush flowers throughout the summer, normally in shades of pink and red. There varieties for the rock garden, border and even amphibious ones for the pond.

Whilst they prefer moist soil most will tolerate dry conditions but won't spread so much. Dead head spent blooms by pulling off the flowering stem at its base. This will ensure further flowers throughout the summer.

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.

Persicaria flowers are very attractive to bees and hoverflies.

Exotic looking but perfectly hardy with us. The leaves keep their best colour and patterning in light shade.  Up to 2ft tall but we keep it short by pinching out the tips regularly.  The small clusters of pink-white flowers are unremarkable but don't spoil the show!
