Yellow Pond Lily - Nuphar lutea (L.) Sm.
Yellow Pond Lily (Brandy-bottle, bullhead lily, Nuphar variegatum, spatterdock, yellow cowlily) also known as Nuphar lutea (L.) Sm. Is a flowering aquatic ornamental plant that is a popular choice for use in water features such as ponds, still pools, and grottos. A perennial, it can grow to 60 cm in height and can spread up to 2 meters on the water surface without trimming. The plant is characterized by large leaves that are accented by fragrant cup shaped bright yellow-green flowers, which feature small scale like petals. The flowers emit a strong perfume that is sweet and buttery. It is easily cultivated in any still water such as ponds and lakes, but it can also be found thriving in slow moving streams and creeping creeks. While the plant is native to the Eastern United States, it has been naturalized to Africa, the West Indies, Europe, the Temperate Zone of Asia, and the remainder of North America. It has never successfully taken hold in Hawaii or Alaska, but can be found in the remaining 48 states. The best zones are 4-10. It may become weedy in some environments, but it is not considered invasive in most areas. It performs best in 1-3 feet of water and prefer full sun, but can tolerate part shade. The soil preference is wet and sandy, poor soil is tolerated well. While it is not considered invasive it can be very hard to eradicate if desired. It is self-regenerating via sprouting from any portion of its rhizome which may remain deep in the soil. This plant is a wonderful choice for those who are looking for an aquatic that requires very little maintenance and provides a soft spark of color with a strong perfume. It can be planted in small containers such as tubs or float pans to provide better control. Cultivation can occur by spreading seed across the water surface where they find their own germination spot.
