Flowering Months
Throughout summer, Persicaria bistorta produces upright stems topped with prominent mauve-pink flower spikes. The green leaves are conspicuously veined, creating large spreading clumps of foliage. Common Bistort is an astonishingly resilient hardy perennial that will look after itself once established. Give it plenty of space to wander and let it form natural colonies for the most impressive display. Height: 75cm (30"). Spread: 90cm (36"). Planting depth: Zones 1 & 2 to 15cm (6") below water level.

Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.

How to Grow
Persicaria bistorta prefers a fertile moist soil, but once established, will happily tolerate most conditions from boggy soils and pond margins to dry conditions. Plant Bistort in sun or semi shade. When grown in ponds, plant Persicaria to a maximum depth of up to 15cm (6") below water level.
More Info
Once established, Persicaria is undemanding and requires little attention. Lift and divide overcrowded clumps in autumn or spring to maintain vigour and keep plants within their allotted space.
