Persicaria amplexicaulis (Knotweed) - Red-flowering perennial 10-25cm

Knotweed (Persicaria amplexicaulis) is a robust perennial with intensely red, spike-shaped flowers. The plant captivates with its long flowering period from summer to autumn and is excellently suited for beds, borders, and cut flower production. With a growth height of 10–25 cm in this delivery size, the perennial develops into a bushy, compact plant. It prefers sunny to semi-shady locations and thrives particularly well in moist, nutrient-rich soils. Knotweed is low-maintenance, winter-hardy, and attracts bees and other pollinators. Pruning in spring promotes denser growth and richer flowering. Ideal for naturalistic gardens and as a structural plant in modern planting concepts.
