Description
The Yellow Water Lily (Nuphar lutea) is a native floating-leaf plant that roots in marshes, ponds, and slow-moving waters. From the lakebed it produces leather‑like, heart‑shaped floating leaves and, from June to August, round, bright yellow flowers that rise to the surface. The plant grows vigorously and requires ample space and water depth; small ornamental ponds are quickly overtaken. All parts of the plant, especially the thick rhizome, are toxic and should not be ingested. In many parts of Germany the species is protected, so it should only be used as a cultivated pond plant, not harvested from the wild.
Care instructions
Plant the rhizome in a potting basket filled with loamy pond soil and submerge it in 60 to 150 cm of water. The Yellow Water Lily prefers a sunny to partially shaded, calm location with no strong currents. In late summer remove yellowed leaves and faded stems to reduce nutrient runoff. Every three to four years, divide the rhizome to keep the growth compact and the flowering abundant. The plant survives winter beneath the water surface as long as the roots do not freeze.
