Purple Loosestrife

Purple Loosestrife, also known as Lythrum salicaria, is a beautiful flowering pond plant that brings strong colour and natural height to pond edges, wet borders, and waterside planting areas. Its tall stems carry bright purple pink flower spikes in summer, creating a vivid display that attracts attention without looking too formal.

This hardy marginal plant is ideal for wet soil, bog gardens, pond margins, stream edges, and damp garden areas where the soil stays consistently moist. Purple Loosestrife looks especially good in natural ponds, wildlife ponds, wet meadow style planting, cottage gardens, and decorative water gardens where a soft, colourful and natural look is desired.

For best results, plant Purple Loosestrife in full sun or partial shade, directly into moist soil or in an aquatic planting basket placed at the pond edge. Once established, it forms a strong clump of upright stems and flowers reliably each summer. Removing faded flower spikes can help keep the plant tidy and encourage a cleaner appearance through the season.

Lythrum salicaria is a hardy perennial wetland plant suitable for moist soils, boggy ground, and shallow water planting. It usually reaches around 80 to 120 cm in height, depending on growing conditions. The recommended planting depth is approximately 0 to 10 cm below the water surface, making it suitable for pond shelves, wet banks, bog gardens, damp borders, and natural pond edge planting.

This species produces narrow green leaves and tall spikes of purple pink flowers, usually from June to August. It performs best in fertile, consistently moist substrates and is especially useful as a vertical flowering accent in naturalistic aquatic planting schemes, wildlife friendly gardens, and wetland style planting designs.

Purple Loosestrife is a good choice for customers looking for a hardy pond plant, purple flowering marginal plant, aquatic plant for wet soil, plant for pond edges, or colourful perennial for bog gardens and natural water garden planting.
