Landscape Value: Great waterside plant for large landscapes. Thrives in the damp or mucky banks of ponds, lakes and slow-moving streams.

A sprawling, shrubby perennial with willow-like leaves and arching stems that grow to 9 feet long and often root at the tips. Bell-shaped, deep-pink flowers (1″ across) bloom in dense clusters in the axils of upper leaves from July to September. Foliage turns shades of red, orange and yellow in the fall. Arching stems can form sizeable patches at the edges of lakes and slow-moving streams. Stems are ornamentally attractive as they arch over water. Where a stem touches water, air-filled, spongy tissue develops and buoys the stem until it roots and forms a new arching stem. Self-rooting stem tips can be removed and transplanted. Larval host for Hydrangea Sphinx and Waterwillow Stem Borer moths. Tolerates standing water up to 24 inches.

Note: Although in the same family, this plant is NOT the invasive purple loosestrife (Lythrum salicaria). Nor is it related to willows, despite the willow-like leaves.
