Persicaria meisneriana, with no widely recognized common name, is a perennial herb that is part of the Polygonaceae family. This species is native to South America. It typically grows to a height of 20-60 cm (8-24 inches) and spreads out to form dense clumps. Persicaria meisneriana is characterized by its lance-shaped leaves and spikes of small, pink to white flowers that bloom in mid to late summer. The flowers are modest in size but can be quite numerous, creating a soft, brush-like appearance.

In cultivation, Persicaria meisneriana is valued for its ability to thrive in damp conditions and its use as a ground cover or border plant in garden settings. It is relatively low-maintenance, requiring consistently moist soil and partial to full sun exposure. While it is not particularly prone to diseases, it can suffer from rust or mildew if conditions are too damp and air circulation is poor. Gardeners should be aware that some Persicaria species can be aggressive spreaders, but P. meisneriana is generally well-behaved in the garden. It is not known for any significant problems with pests or diseases, and it does not have aggressive roots.CC BY-SA 4.0
