Can you grow Persicaria from seed?
How to Grow Persicaria from Seed. Sow indoors. Surface sow onto moist well-drained seed compost, just covering with a little soil at an ideal temperature of 65-68°F (18-22°C). Germination can take anywhere between 21-60 days. Choose a location that receives at least 6 hours of sunlight per day. Soil Quality: Well-draining soil is crucial for persicaria. Amend heavy or compacted soil with organic matter to improve drainage. Spring or Autumn: Plant persicaria in the spring or autumn when the soil is workable, and temperatures are mild.Sowing: Sow in late summer/autumn and late winter/late spring. Persicaria need a period of cold to enable them to germinate. Sow at temperatures of around 18 to 22°C (64 to 71°F), covering them with a thin layer of compost. The compost should be kept moist but not wet at all times.Persicaria can be propagated by the division of established clumps in spring or autumn (every three or so years). As well as providing new plants, this also maintains the health and vigour of existing clumps and restricts their spread.

How do you grow Persicaria from seed?
Sowing in the garden can also be done in late summer/autumn, then just let winter come over it, germination takes place in spring. Early budding gives shorter, more branched plants. All our flower seeds produce flowers that are suitable for use as cut flowers. If you’re sowing your seeds into the ground and not into a container, taking the time to prepare the site will give you a much higher chance of growing a gorgeous crop. As long as the soil is warm and moist, seed can be sown and it should germinate quickly.For a natural effect, it’s best to scatter (broadcast) the seeds rather than sowing in straight lines. The easiest way to get an even distribution is to mix the seeds with a small quantity of dry sand – you can then see where and how densely you’ve sown.
Do Persicaria self seed?
Persicaria wallechii Easy to grow from seed, it will self seed freely in well drained soil. The tall narrow flowers of Persciaria lend themselves to the planting scheme known as ‘prairie planting’ mixing wispy grasses and late-flowering perennials in large drifts to create a naturalistic appearance. For a contrasting look, combine with tall grasses, Rudbeckia, or Echinacea for bold textures and colours in the garden. Persicaria (Bistort) is a versatile, low-maintenance perennial that brings vibrant colour and texture to gardens.
