Description
Purple loosestrife is a native riparian perennial that bears purple flower spikes from June to September, making it one of the most striking summer flowers along pond edges. In the wild it is found along stream runs, banks, and damp meadows, making it an excellent choice for garden ponds or wet areas in beds. Bees, bumblebees, and butterflies visit the flowers throughout the summer, making the species a valuable pollinator-friendly plant. The botanical name is Lythrum salicaria; the German name is sufficient for everyday gardening.
Care instructions
Plant purple loosestrife in a sunny to partially shaded spot with consistently moist to wet soil, such as near a pond or in a marshy zone. Set out seedlings in spring, from mid‑May (week 20), at spacing of 40 to 50 cm to allow the clumps to develop well. Water heavily during dry summer weeks, as the plant tolerates waterlogging better than drought. Cut back the spent stems in autumn or early spring, so that the seed heads provide additional food for birds over winter. The wild form is hardy and is usually cultivated without winter protection.
