Lysimachia clethroides

Chinese loosestrife

Product Image
Tall stems of narrow, mid-green leaves are topped with arching spikes of tiny white flowers in July and August. Chinese loostrife looks striking towards the back of a moist, well-drained border or beside water in sun or partial shade. But be warned, it can be invasive and its spread needs to be reduced each year.
