A colourful plant for watersides, pond banks and woodland borders where the soil remains slightly moist, this clump forming perennial produces tall spikes of reddish-purple star shaped summer flowers. A relatively fast-grower, the flowers are also rich in nectar, so are popular with the pollinators.
Plant Lythrum in reliably moist soil in full sun, where it will produce tall, colourful flower spikes through summer. It also grows well in a pond basket positioned at the water’s edge, with the crown just above the waterline
Apply a generous mulch of well-rotted compost around the base in early spring to feed the soil and plant, and help retain moisture. Deadhead or remove fading flower spikes if you want to limit self-seeding and keep growth tidy.
Cut back spent stems to ground level in late autumn to prepare for fresh growth the following spring.

Surface-sow directly onto trays filled with good seed compost in March or April, and maintain temperatures around 20C. When seedlings are large enough to handle, pot them up individually and grow them on. Gradually harden off before planting outside after risk of frost. Autumn-sown seedlings (August to October) should be overwintered in a coldframe before planting out the following spring.
- CAUTION toxic if eaten/skin & eye irritant
