Persicaria amphibia
amphibious bistort
A versatile bog garden or aquatic perennial, Persicaria amphibia boasts glossy, dark green leaves with paler veins that create an eye-catching contrast. Its pink, fluffy flowers emerge from short spikes, adding a delicate touch to any aquatic setting from mid-summer to early autumn. Adaptability is key for this slow-growing plant, thriving in various conditions, whether in full sun, part-shade, or even moderate shade. While it can flourish with its foliage above water or floating on the surface, its preferred habitat is deeper water with ample sunlight, where it unveils its charming blooms. This native beauty not only enhances the aesthetic of water features but also provides essential surface cover in natural settings, making it a valuable addition for wildlife ponds.
How to care for Persicaria amphibia:
If intending to grow as a boggy/marginal aquatic, plant out in reliably moist or boggy soil, or pot up into a pond basket and place at the margins of a pond at a depth of 0-80cm (0-30in). Divide regularly to avoid congestion. May have the potential to become invasive if growth is not checked periodically. Choose our 9cm pot range for planting above the waterline, or our aquatic pot range for at or below the water's surface.
