The decorative purple or purple-pink flowers appear on erect spikes. They bloom in summer

They are used next to ponds, lakes and waterways, in borders and flowerbeds and in pots for patios and terraces. They are plants that tend to be invasive and their sale is prohibited in some countries.

Lythrum salicaria needs full sun exposure and a warm-temperate climate. They resist light frosts.

The soil must be loamy and not well drained to retain moisture.

Water frequently so that the substrate always remains damp, even if it is waterlogged. They do not resist drought.

They do not need fertilizers.

Prune wilted inflorescences to prevent fruit bearing and self-propagation (remember they are invasive).

They are resistant plants to the usual pests and diseases but can be attacked by snails and slugs.

They are propagated by division of the plant in spring. They tend to self-propagate from seeds.
