About This Species

Yellow loosestrife is a fast-spreading perennial plant native to central Europe and Turkey. It can form dense clumps that spread out over large areas, crowding out native plants. Yellow loosestrife prefers moist soils, and is typically found in wet roadsides, ditches, along shorelines and wetlands.

How to Identify

Yellow loosestrife forms a bushy clump of leaves, with loose spikes of bright yellow star-shaped flowers that bloom in early to mid-summer. Leaves are light green, with serrated edges, and range from 3-10 cm long. Stems grow 60-150 cm tall and are sturdy, hairy and dotted with red or black spots.
